"pathlib" --- Object-oriented filesystem paths
**********************************************

Added in version 3.4.

**Source code:** Lib/pathlib/

======================================================================

This module offers classes representing filesystem paths with
semantics appropriate for different operating systems.  Path classes
are divided between pure paths, which provide purely computational
operations without I/O, and concrete paths, which inherit from pure
paths but also provide I/O operations.

[image: Inheritance diagram showing the classes available in pathlib.
The most basic class is PurePath, which has three direct subclasses:
PurePosixPath, PureWindowsPath, and Path. Further to these four
classes, there are two classes that use multiple inheritance:
PosixPath subclasses PurePosixPath and Path, and WindowsPath
subclasses PureWindowsPath and Path.][image]

If you've never used this module before or just aren't sure which
class is right for your task, "Path" is most likely what you need. It
instantiates a concrete path for the platform the code is running on.

Pure paths are useful in some special cases; for example:

1. If you want to manipulate Windows paths on a Unix machine (or vice
   versa). You cannot instantiate a "WindowsPath" when running on
   Unix, but you can instantiate "PureWindowsPath".

2. You want to make sure that your code only manipulates paths without
   actually accessing the OS. In this case, instantiating one of the
   pure classes may be useful since those simply don't have any OS-
   accessing operations.

See also:

  **PEP 428**: The pathlib module -- object-oriented filesystem paths.

See also:

  For low-level path manipulation on strings, you can also use the
  "os.path" module.


Basic use
=========

Importing the main class:

   >>> from pathlib import Path

Listing subdirectories:

   >>> p = Path('.')
   >>> [x for x in p.iterdir() if x.is_dir()]
   [PosixPath('.hg'), PosixPath('docs'), PosixPath('dist'),
    PosixPath('__pycache__'), PosixPath('build')]

Listing Python source files in this directory tree:

   >>> list(p.glob('**/*.py'))
   [PosixPath('test_pathlib.py'), PosixPath('setup.py'),
    PosixPath('pathlib.py'), PosixPath('docs/conf.py'),
    PosixPath('build/lib/pathlib.py')]

Navigating inside a directory tree:

   >>> p = Path('/etc')
   >>> q = p / 'init.d' / 'reboot'
   >>> q
   PosixPath('/etc/init.d/reboot')
   >>> q.resolve()
   PosixPath('/etc/rc.d/init.d/halt')

Querying path properties:

   >>> q.exists()
   True
   >>> q.is_dir()
   False

Opening a file:

   >>> with q.open() as f: f.readline()
   ...
   '#!/bin/bash\n'


Exceptions
==========

exception pathlib.UnsupportedOperation

   An exception inheriting "NotImplementedError" that is raised when
   an unsupported operation is called on a path object.

   Added in version 3.13.


Pure paths
==========

Pure path objects provide path-handling operations which don't
actually access a filesystem.  There are three ways to access these
classes, which we also call *flavours*:

class pathlib.PurePath(*pathsegments)

   A generic class that represents the system's path flavour
   (instantiating it creates either a "PurePosixPath" or a
   "PureWindowsPath"):

      >>> PurePath('setup.py')      # Running on a Unix machine
      PurePosixPath('setup.py')

   Each element of *pathsegments* can be either a string representing
   a path segment, or an object implementing the "os.PathLike"
   interface where the "__fspath__()" method returns a string, such as
   another path object:

      >>> PurePath('foo', 'some/path', 'bar')
      PurePosixPath('foo/some/path/bar')
      >>> PurePath(Path('foo'), Path('bar'))
      PurePosixPath('foo/bar')

   When *pathsegments* is empty, the current directory is assumed:

      >>> PurePath()
      PurePosixPath('.')

   If a segment is an absolute path, all previous segments are ignored
   (like "os.path.join()"):

      >>> PurePath('/etc', '/usr', 'lib64')
      PurePosixPath('/usr/lib64')
      >>> PureWindowsPath('c:/Windows', 'd:bar')
      PureWindowsPath('d:bar')

   On Windows, the drive is not reset when a rooted relative path
   segment (e.g., "r'\foo'") is encountered:

      >>> PureWindowsPath('c:/Windows', '/Program Files')
      PureWindowsPath('c:/Program Files')

   Spurious slashes and single dots are collapsed, but double dots
   ("'..'") and leading double slashes ("'//'") are not, since this
   would change the meaning of a path for various reasons (e.g.
   symbolic links, UNC paths):

      >>> PurePath('foo//bar')
      PurePosixPath('foo/bar')
      >>> PurePath('//foo/bar')
      PurePosixPath('//foo/bar')
      >>> PurePath('foo/./bar')
      PurePosixPath('foo/bar')
      >>> PurePath('foo/../bar')
      PurePosixPath('foo/../bar')

   (a naïve approach would make "PurePosixPath('foo/../bar')"
   equivalent to "PurePosixPath('bar')", which is wrong if "foo" is a
   symbolic link to another directory)

   Pure path objects implement the "os.PathLike" interface, allowing
   them to be used anywhere the interface is accepted.

   Changed in version 3.6: Added support for the "os.PathLike"
   interface.

class pathlib.PurePosixPath(*pathsegments)

   A subclass of "PurePath", this path flavour represents non-Windows
   filesystem paths:

      >>> PurePosixPath('/etc/hosts')
      PurePosixPath('/etc/hosts')

   *pathsegments* is specified similarly to "PurePath".

class pathlib.PureWindowsPath(*pathsegments)

   A subclass of "PurePath", this path flavour represents Windows
   filesystem paths, including UNC paths:

      >>> PureWindowsPath('c:/', 'Users', 'Ximénez')
      PureWindowsPath('c:/Users/Ximénez')
      >>> PureWindowsPath('//server/share/file')
      PureWindowsPath('//server/share/file')

   *pathsegments* is specified similarly to "PurePath".

Regardless of the system you're running on, you can instantiate all of
these classes, since they don't provide any operation that does system
calls.


General properties
------------------

Paths are immutable and *hashable*.  Paths of a same flavour are
comparable and orderable.  These properties respect the flavour's
case-folding semantics:

   >>> PurePosixPath('foo') == PurePosixPath('FOO')
   False
   >>> PureWindowsPath('foo') == PureWindowsPath('FOO')
   True
   >>> PureWindowsPath('FOO') in { PureWindowsPath('foo') }
   True
   >>> PureWindowsPath('C:') < PureWindowsPath('d:')
   True

Paths of a different flavour compare unequal and cannot be ordered:

   >>> PureWindowsPath('foo') == PurePosixPath('foo')
   False
   >>> PureWindowsPath('foo') < PurePosixPath('foo')
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
   TypeError: '<' not supported between instances of 'PureWindowsPath' and 'PurePosixPath'


Operators
---------

The slash operator helps create child paths, like "os.path.join()". If
the argument is an absolute path, the previous path is ignored. On
Windows, the drive is not reset when the argument is a rooted relative
path (e.g., "r'\foo'"):

   >>> p = PurePath('/etc')
   >>> p
   PurePosixPath('/etc')
   >>> p / 'init.d' / 'apache2'
   PurePosixPath('/etc/init.d/apache2')
   >>> q = PurePath('bin')
   >>> '/usr' / q
   PurePosixPath('/usr/bin')
   >>> p / '/an_absolute_path'
   PurePosixPath('/an_absolute_path')
   >>> PureWindowsPath('c:/Windows', '/Program Files')
   PureWindowsPath('c:/Program Files')

A path object can be used anywhere an object implementing
"os.PathLike" is accepted:

   >>> import os
   >>> p = PurePath('/etc')
   >>> os.fspath(p)
   '/etc'

The string representation of a path is the raw filesystem path itself
(in native form, e.g. with backslashes under Windows), which you can
pass to any function taking a file path as a string:

   >>> p = PurePath('/etc')
   >>> str(p)
   '/etc'
   >>> p = PureWindowsPath('c:/Program Files')
   >>> str(p)
   'c:\\Program Files'

Similarly, calling "bytes" on a path gives the raw filesystem path as
a bytes object, as encoded by "os.fsencode()":

   >>> bytes(p)
   b'/etc'

Note:

  Calling "bytes" is only recommended under Unix.  Under Windows, the
  unicode form is the canonical representation of filesystem paths.


Accessing individual parts
--------------------------

To access the individual "parts" (components) of a path, use the
following property:

PurePath.parts

   A tuple giving access to the path's various components:

      >>> p = PurePath('/usr/bin/python3')
      >>> p.parts
      ('/', 'usr', 'bin', 'python3')

      >>> p = PureWindowsPath('c:/Program Files/PSF')
      >>> p.parts
      ('c:\\', 'Program Files', 'PSF')

   (note how the drive and local root are regrouped in a single part)


Methods and properties
----------------------

Pure paths provide the following methods and properties:

PurePath.parser

   The implementation of the "os.path" module used for low-level path
   parsing and joining: either "posixpath" or "ntpath".

   Added in version 3.13.

PurePath.drive

   A string representing the drive letter or name, if any:

      >>> PureWindowsPath('c:/Program Files/').drive
      'c:'
      >>> PureWindowsPath('/Program Files/').drive
      ''
      >>> PurePosixPath('/etc').drive
      ''

   UNC shares are also considered drives:

      >>> PureWindowsPath('//host/share/foo.txt').drive
      '\\\\host\\share'

PurePath.root

   A string representing the (local or global) root, if any:

      >>> PureWindowsPath('c:/Program Files/').root
      '\\'
      >>> PureWindowsPath('c:Program Files/').root
      ''
      >>> PurePosixPath('/etc').root
      '/'

   UNC shares always have a root:

      >>> PureWindowsPath('//host/share').root
      '\\'

   If the path starts with more than two successive slashes,
   "PurePosixPath" collapses them:

      >>> PurePosixPath('//etc').root
      '//'
      >>> PurePosixPath('///etc').root
      '/'
      >>> PurePosixPath('////etc').root
      '/'

   Note:

     This behavior conforms to *The Open Group Base Specifications
     Issue 6*, paragraph 4.11 Pathname Resolution:*"A pathname that
     begins with two successive slashes may be interpreted in an
     implementation-defined manner, although more than two leading
     slashes shall be treated as a single slash."*

PurePath.anchor

   The concatenation of the drive and root:

      >>> PureWindowsPath('c:/Program Files/').anchor
      'c:\\'
      >>> PureWindowsPath('c:Program Files/').anchor
      'c:'
      >>> PurePosixPath('/etc').anchor
      '/'
      >>> PureWindowsPath('//host/share').anchor
      '\\\\host\\share\\'

PurePath.parents

   An immutable sequence providing access to the logical ancestors of
   the path:

      >>> p = PureWindowsPath('c:/foo/bar/setup.py')
      >>> p.parents[0]
      PureWindowsPath('c:/foo/bar')
      >>> p.parents[1]
      PureWindowsPath('c:/foo')
      >>> p.parents[2]
      PureWindowsPath('c:/')

   Changed in version 3.10: The parents sequence now supports *slices*
   and negative index values.

PurePath.parent

   The logical parent of the path:

      >>> p = PurePosixPath('/a/b/c/d')
      >>> p.parent
      PurePosixPath('/a/b/c')

   You cannot go past an anchor, or empty path:

      >>> p = PurePosixPath('/')
      >>> p.parent
      PurePosixPath('/')
      >>> p = PurePosixPath('.')
      >>> p.parent
      PurePosixPath('.')

   Note:

     This is a purely lexical operation, hence the following
     behaviour:

        >>> p = PurePosixPath('foo/..')
        >>> p.parent
        PurePosixPath('foo')

     If you want to walk an arbitrary filesystem path upwards, it is
     recommended to first call "Path.resolve()" so as to resolve
     symlinks and eliminate "".."" components.

PurePath.name

   A string representing the final path component, excluding the drive
   and root, if any:

      >>> PurePosixPath('my/library/setup.py').name
      'setup.py'

   UNC drive names are not considered:

      >>> PureWindowsPath('//some/share/setup.py').name
      'setup.py'
      >>> PureWindowsPath('//some/share').name
      ''

PurePath.suffix

   The last dot-separated portion of the final component, if any:

      >>> PurePosixPath('my/library/setup.py').suffix
      '.py'
      >>> PurePosixPath('my/library.tar.gz').suffix
      '.gz'
      >>> PurePosixPath('my/library').suffix
      ''

   This is commonly called the file extension.

   Changed in version 3.14: A single dot (""."") is considered a valid
   suffix.

PurePath.suffixes

   A list of the path's suffixes, often called file extensions:

      >>> PurePosixPath('my/library.tar.gar').suffixes
      ['.tar', '.gar']
      >>> PurePosixPath('my/library.tar.gz').suffixes
      ['.tar', '.gz']
      >>> PurePosixPath('my/library').suffixes
      []

   Changed in version 3.14: A single dot (""."") is considered a valid
   suffix.

PurePath.stem

   The final path component, without its suffix:

      >>> PurePosixPath('my/library.tar.gz').stem
      'library.tar'
      >>> PurePosixPath('my/library.tar').stem
      'library'
      >>> PurePosixPath('my/library').stem
      'library'

PurePath.as_posix()

   Return a string representation of the path with forward slashes
   ("/"):

      >>> p = PureWindowsPath('c:\\windows')
      >>> str(p)
      'c:\\windows'
      >>> p.as_posix()
      'c:/windows'

PurePath.is_absolute()

   Return whether the path is absolute or not.  A path is considered
   absolute if it has both a root and (if the flavour allows) a drive:

      >>> PurePosixPath('/a/b').is_absolute()
      True
      >>> PurePosixPath('a/b').is_absolute()
      False

      >>> PureWindowsPath('c:/a/b').is_absolute()
      True
      >>> PureWindowsPath('/a/b').is_absolute()
      False
      >>> PureWindowsPath('c:').is_absolute()
      False
      >>> PureWindowsPath('//some/share').is_absolute()
      True

PurePath.is_relative_to(other)

   Return whether or not this path is relative to the *other* path.

   >>> p = PurePath('/etc/passwd')
   >>> p.is_relative_to('/etc')
   True
   >>> p.is_relative_to('/usr')
   False

   This method is string-based; it neither accesses the filesystem nor
   treats "".."" segments specially. The following code is equivalent:

   >>> u = PurePath('/usr')
   >>> u == p or u in p.parents
   False

   Added in version 3.9.

   Deprecated since version 3.12, removed in version 3.14: Passing
   additional arguments is deprecated; if supplied, they are joined
   with *other*.

PurePath.is_reserved()

   With "PureWindowsPath", return "True" if the path is considered
   reserved under Windows, "False" otherwise.  With "PurePosixPath",
   "False" is always returned.

   Changed in version 3.13: Windows path names that contain a colon,
   or end with a dot or a space, are considered reserved. UNC paths
   may be reserved.

   Deprecated since version 3.13, will be removed in version 3.15:
   This method is deprecated; use "os.path.isreserved()" to detect
   reserved paths on Windows.

PurePath.joinpath(*pathsegments)

   Calling this method is equivalent to combining the path with each
   of the given *pathsegments* in turn:

      >>> PurePosixPath('/etc').joinpath('passwd')
      PurePosixPath('/etc/passwd')
      >>> PurePosixPath('/etc').joinpath(PurePosixPath('passwd'))
      PurePosixPath('/etc/passwd')
      >>> PurePosixPath('/etc').joinpath('init.d', 'apache2')
      PurePosixPath('/etc/init.d/apache2')
      >>> PureWindowsPath('c:').joinpath('/Program Files')
      PureWindowsPath('c:/Program Files')

PurePath.full_match(pattern, *, case_sensitive=None)

   Match this path against the provided glob-style pattern.  Return
   "True" if matching is successful, "False" otherwise.  For example:

      >>> PurePath('a/b.py').full_match('a/*.py')
      True
      >>> PurePath('a/b.py').full_match('*.py')
      False
      >>> PurePath('/a/b/c.py').full_match('/a/**')
      True
      >>> PurePath('/a/b/c.py').full_match('**/*.py')
      True

   See also: Pattern language documentation.

   As with other methods, case-sensitivity follows platform defaults:

      >>> PurePosixPath('b.py').full_match('*.PY')
      False
      >>> PureWindowsPath('b.py').full_match('*.PY')
      True

   Set *case_sensitive* to "True" or "False" to override this
   behaviour.

   Added in version 3.13.

PurePath.match(pattern, *, case_sensitive=None)

   Match this path against the provided non-recursive glob-style
   pattern. Return "True" if matching is successful, "False"
   otherwise.

   This method is similar to "full_match()", but empty patterns aren't
   allowed ("ValueError" is raised), the recursive wildcard ""**""
   isn't supported (it acts like non-recursive ""*""), and if a
   relative pattern is provided, then matching is done from the right:

      >>> PurePath('a/b.py').match('*.py')
      True
      >>> PurePath('/a/b/c.py').match('b/*.py')
      True
      >>> PurePath('/a/b/c.py').match('a/*.py')
      False

   Changed in version 3.12: The *pattern* parameter accepts a *path-
   like object*.

   Changed in version 3.12: The *case_sensitive* parameter was added.

PurePath.relative_to(other, walk_up=False)

   Compute a version of this path relative to the path represented by
   *other*.  If it's impossible, "ValueError" is raised:

      >>> p = PurePosixPath('/etc/passwd')
      >>> p.relative_to('/')
      PurePosixPath('etc/passwd')
      >>> p.relative_to('/etc')
      PurePosixPath('passwd')
      >>> p.relative_to('/usr')
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "pathlib.py", line 941, in relative_to
          raise ValueError(error_message.format(str(self), str(formatted)))
      ValueError: '/etc/passwd' is not in the subpath of '/usr' OR one path is relative and the other is absolute.

   When *walk_up* is false (the default), the path must start with
   *other*. When the argument is true, ".." entries may be added to
   form the relative path. In all other cases, such as the paths
   referencing different drives, "ValueError" is raised.:

      >>> p.relative_to('/usr', walk_up=True)
      PurePosixPath('../etc/passwd')
      >>> p.relative_to('foo', walk_up=True)
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "pathlib.py", line 941, in relative_to
          raise ValueError(error_message.format(str(self), str(formatted)))
      ValueError: '/etc/passwd' is not on the same drive as 'foo' OR one path is relative and the other is absolute.

   Warning:

     This function is part of "PurePath" and works with strings. It
     does not check or access the underlying file structure. This can
     impact the *walk_up* option as it assumes that no symlinks are
     present in the path; call "resolve()" first if necessary to
     resolve symlinks.

   Changed in version 3.12: The *walk_up* parameter was added (old
   behavior is the same as "walk_up=False").

   Deprecated since version 3.12, removed in version 3.14: Passing
   additional positional arguments is deprecated; if supplied, they
   are joined with *other*.

PurePath.with_name(name)

   Return a new path with the "name" changed.  If the original path
   doesn't have a name, ValueError is raised:

      >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
      >>> p.with_name('setup.py')
      PureWindowsPath('c:/Downloads/setup.py')
      >>> p = PureWindowsPath('c:/')
      >>> p.with_name('setup.py')
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "/home/antoine/cpython/default/Lib/pathlib.py", line 751, in with_name
          raise ValueError("%r has an empty name" % (self,))
      ValueError: PureWindowsPath('c:/') has an empty name

PurePath.with_stem(stem)

   Return a new path with the "stem" changed.  If the original path
   doesn't have a name, ValueError is raised:

      >>> p = PureWindowsPath('c:/Downloads/draft.txt')
      >>> p.with_stem('final')
      PureWindowsPath('c:/Downloads/final.txt')
      >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
      >>> p.with_stem('lib')
      PureWindowsPath('c:/Downloads/lib.gz')
      >>> p = PureWindowsPath('c:/')
      >>> p.with_stem('')
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "/home/antoine/cpython/default/Lib/pathlib.py", line 861, in with_stem
          return self.with_name(stem + self.suffix)
        File "/home/antoine/cpython/default/Lib/pathlib.py", line 851, in with_name
          raise ValueError("%r has an empty name" % (self,))
      ValueError: PureWindowsPath('c:/') has an empty name

   Added in version 3.9.

PurePath.with_suffix(suffix)

   Return a new path with the "suffix" changed.  If the original path
   doesn't have a suffix, the new *suffix* is appended instead.  If
   the *suffix* is an empty string, the original suffix is removed:

      >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
      >>> p.with_suffix('.bz2')
      PureWindowsPath('c:/Downloads/pathlib.tar.bz2')
      >>> p = PureWindowsPath('README')
      >>> p.with_suffix('.txt')
      PureWindowsPath('README.txt')
      >>> p = PureWindowsPath('README.txt')
      >>> p.with_suffix('')
      PureWindowsPath('README')

   Changed in version 3.14: A single dot (""."") is considered a valid
   suffix. In previous versions, "ValueError" is raised if a single
   dot is supplied.

PurePath.with_segments(*pathsegments)

   Create a new path object of the same type by combining the given
   *pathsegments*. This method is called whenever a derivative path is
   created, such as from "parent" and "relative_to()". Subclasses may
   override this method to pass information to derivative paths, for
   example:

      from pathlib import PurePosixPath

      class MyPath(PurePosixPath):
          def __init__(self, *pathsegments, session_id):
              super().__init__(*pathsegments)
              self.session_id = session_id

          def with_segments(self, *pathsegments):
              return type(self)(*pathsegments, session_id=self.session_id)

      etc = MyPath('/etc', session_id=42)
      hosts = etc / 'hosts'
      print(hosts.session_id)  # 42

   Added in version 3.12.


Concrete paths
==============

Concrete paths are subclasses of the pure path classes.  In addition
to operations provided by the latter, they also provide methods to do
system calls on path objects.  There are three ways to instantiate
concrete paths:

class pathlib.Path(*pathsegments)

   A subclass of "PurePath", this class represents concrete paths of
   the system's path flavour (instantiating it creates either a
   "PosixPath" or a "WindowsPath"):

      >>> Path('setup.py')
      PosixPath('setup.py')

   *pathsegments* is specified similarly to "PurePath".

class pathlib.PosixPath(*pathsegments)

   A subclass of "Path" and "PurePosixPath", this class represents
   concrete non-Windows filesystem paths:

      >>> PosixPath('/etc/hosts')
      PosixPath('/etc/hosts')

   *pathsegments* is specified similarly to "PurePath".

   Changed in version 3.13: Raises "UnsupportedOperation" on Windows.
   In previous versions, "NotImplementedError" was raised instead.

class pathlib.WindowsPath(*pathsegments)

   A subclass of "Path" and "PureWindowsPath", this class represents
   concrete Windows filesystem paths:

      >>> WindowsPath('c:/', 'Users', 'Ximénez')
      WindowsPath('c:/Users/Ximénez')

   *pathsegments* is specified similarly to "PurePath".

   Changed in version 3.13: Raises "UnsupportedOperation" on non-
   Windows platforms. In previous versions, "NotImplementedError" was
   raised instead.

You can only instantiate the class flavour that corresponds to your
system (allowing system calls on non-compatible path flavours could
lead to bugs or failures in your application):

   >>> import os
   >>> os.name
   'posix'
   >>> Path('setup.py')
   PosixPath('setup.py')
   >>> PosixPath('setup.py')
   PosixPath('setup.py')
   >>> WindowsPath('setup.py')
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File "pathlib.py", line 798, in __new__
       % (cls.__name__,))
   UnsupportedOperation: cannot instantiate 'WindowsPath' on your system

Some concrete path methods can raise an "OSError" if a system call
fails (for example because the path doesn't exist).


Parsing and generating URIs
---------------------------

Concrete path objects can be created from, and represented as, 'file'
URIs conforming to **RFC 8089**.

Note:

  File URIs are not portable across machines with different filesystem
  encodings.

classmethod Path.from_uri(uri)

   Return a new path object from parsing a 'file' URI. For example:

      >>> p = Path.from_uri('file:///etc/hosts')
      PosixPath('/etc/hosts')

   On Windows, DOS device and UNC paths may be parsed from URIs:

      >>> p = Path.from_uri('file:///c:/windows')
      WindowsPath('c:/windows')
      >>> p = Path.from_uri('file://server/share')
      WindowsPath('//server/share')

   Several variant forms are supported:

      >>> p = Path.from_uri('file:////server/share')
      WindowsPath('//server/share')
      >>> p = Path.from_uri('file://///server/share')
      WindowsPath('//server/share')
      >>> p = Path.from_uri('file:c:/windows')
      WindowsPath('c:/windows')
      >>> p = Path.from_uri('file:/c|/windows')
      WindowsPath('c:/windows')

   "ValueError" is raised if the URI does not start with "file:", or
   the parsed path isn't absolute.

   Added in version 3.13.

Path.as_uri()

   Represent the path as a 'file' URI.  "ValueError" is raised if the
   path isn't absolute.

      >>> p = PosixPath('/etc/passwd')
      >>> p.as_uri()
      'file:///etc/passwd'
      >>> p = WindowsPath('c:/Windows')
      >>> p.as_uri()
      'file:///c:/Windows'

   For historical reasons, this method is also available from
   "PurePath" objects. However, its use of "os.fsencode()" makes it
   strictly impure.


Expanding and resolving paths
-----------------------------

classmethod Path.home()

   Return a new path object representing the user's home directory (as
   returned by "os.path.expanduser()" with "~" construct). If the home
   directory can't be resolved, "RuntimeError" is raised.

      >>> Path.home()
      PosixPath('/home/antoine')

   Added in version 3.5.

Path.expanduser()

   Return a new path with expanded "~" and "~user" constructs, as
   returned by "os.path.expanduser()". If a home directory can't be
   resolved, "RuntimeError" is raised.

      >>> p = PosixPath('~/films/Monty Python')
      >>> p.expanduser()
      PosixPath('/home/eric/films/Monty Python')

   Added in version 3.5.

classmethod Path.cwd()

   Return a new path object representing the current directory (as
   returned by "os.getcwd()"):

      >>> Path.cwd()
      PosixPath('/home/antoine/pathlib')

Path.absolute()

   Make the path absolute, without normalization or resolving
   symlinks. Returns a new path object:

      >>> p = Path('tests')
      >>> p
      PosixPath('tests')
      >>> p.absolute()
      PosixPath('/home/antoine/pathlib/tests')

Path.resolve(strict=False)

   Make the path absolute, resolving any symlinks.  A new path object
   is returned:

      >>> p = Path()
      >>> p
      PosixPath('.')
      >>> p.resolve()
      PosixPath('/home/antoine/pathlib')

   "".."" components are also eliminated (this is the only method to
   do so):

      >>> p = Path('docs/../setup.py')
      >>> p.resolve()
      PosixPath('/home/antoine/pathlib/setup.py')

   If a path doesn't exist or a symlink loop is encountered, and
   *strict* is "True", "OSError" is raised.  If *strict* is "False",
   the path is resolved as far as possible and any remainder is
   appended without checking whether it exists.

   Changed in version 3.6: The *strict* parameter was added (pre-3.6
   behavior is strict).

   Changed in version 3.13: Symlink loops are treated like other
   errors: "OSError" is raised in strict mode, and no exception is
   raised in non-strict mode. In previous versions, "RuntimeError" is
   raised no matter the value of *strict*.

Path.readlink()

   Return the path to which the symbolic link points (as returned by
   "os.readlink()"):

      >>> p = Path('mylink')
      >>> p.symlink_to('setup.py')
      >>> p.readlink()
      PosixPath('setup.py')

   Added in version 3.9.

   Changed in version 3.13: Raises "UnsupportedOperation" if
   "os.readlink()" is not available. In previous versions,
   "NotImplementedError" was raised.


Querying file type and status
-----------------------------

Changed in version 3.8: "exists()", "is_dir()", "is_file()",
"is_mount()", "is_symlink()", "is_block_device()", "is_char_device()",
"is_fifo()", "is_socket()" now return "False" instead of raising an
exception for paths that contain characters unrepresentable at the OS
level.

Changed in version 3.14: The methods given above now return "False"
instead of raising any "OSError" exception from the operating system.
In previous versions, some kinds of "OSError" exception are raised,
and others suppressed. The new behaviour is consistent with
"os.path.exists()", "os.path.isdir()", etc. Use "stat()" to retrieve
the file status without suppressing exceptions.

Path.stat(*, follow_symlinks=True)

   Return an "os.stat_result" object containing information about this
   path, like "os.stat()". The result is looked up at each call to
   this method.

   This method normally follows symlinks; to stat a symlink add the
   argument "follow_symlinks=False", or use "lstat()".

      >>> p = Path('setup.py')
      >>> p.stat().st_size
      956
      >>> p.stat().st_mtime
      1327883547.852554

   Changed in version 3.10: The *follow_symlinks* parameter was added.

Path.lstat()

   Like "Path.stat()" but, if the path points to a symbolic link,
   return the symbolic link's information rather than its target's.

Path.exists(*, follow_symlinks=True)

   Return "True" if the path points to an existing file or directory.
   "False" will be returned if the path is invalid, inaccessible or
   missing. Use "Path.stat()" to distinguish between these cases.

   This method normally follows symlinks; to check if a symlink
   exists, add the argument "follow_symlinks=False".

      >>> Path('.').exists()
      True
      >>> Path('setup.py').exists()
      True
      >>> Path('/etc').exists()
      True
      >>> Path('nonexistentfile').exists()
      False

   Changed in version 3.12: The *follow_symlinks* parameter was added.

Path.is_file(*, follow_symlinks=True)

   Return "True" if the path points to a regular file. "False" will be
   returned if the path is invalid, inaccessible or missing, or if it
   points to something other than a regular file. Use "Path.stat()" to
   distinguish between these cases.

   This method normally follows symlinks; to exclude symlinks, add the
   argument "follow_symlinks=False".

   Changed in version 3.13: The *follow_symlinks* parameter was added.

Path.is_dir(*, follow_symlinks=True)

   Return "True" if the path points to a directory. "False" will be
   returned if the path is invalid, inaccessible or missing, or if it
   points to something other than a directory. Use "Path.stat()" to
   distinguish between these cases.

   This method normally follows symlinks; to exclude symlinks to
   directories, add the argument "follow_symlinks=False".

   Changed in version 3.13: The *follow_symlinks* parameter was added.

Path.is_symlink()

   Return "True" if the path points to a symbolic link, even if that
   symlink is broken. "False" will be returned if the path is invalid,
   inaccessible or missing, or if it points to something other than a
   symbolic link. Use "Path.stat()" to distinguish between these
   cases.

Path.is_junction()

   Return "True" if the path points to a junction, and "False" for any
   other type of file. Currently only Windows supports junctions.

   Added in version 3.12.

Path.is_mount()

   Return "True" if the path is a *mount point*: a point in a file
   system where a different file system has been mounted.  On POSIX,
   the function checks whether *path*'s parent, "path/..", is on a
   different device than *path*, or whether "path/.." and *path* point
   to the same i-node on the same device --- this should detect mount
   points for all Unix and POSIX variants.  On Windows, a mount point
   is considered to be a drive letter root (e.g. "c:\"), a UNC share
   (e.g. "\\server\share"), or a mounted filesystem directory.

   Added in version 3.7.

   Changed in version 3.12: Windows support was added.

Path.is_socket()

   Return "True" if the path points to a Unix socket. "False" will be
   returned if the path is invalid, inaccessible or missing, or if it
   points to something other than a Unix socket. Use "Path.stat()" to
   distinguish between these cases.

Path.is_fifo()

   Return "True" if the path points to a FIFO. "False" will be
   returned if the path is invalid, inaccessible or missing, or if it
   points to something other than a FIFO. Use "Path.stat()" to
   distinguish between these cases.

Path.is_block_device()

   Return "True" if the path points to a block device. "False" will be
   returned if the path is invalid, inaccessible or missing, or if it
   points to something other than a block device. Use "Path.stat()" to
   distinguish between these cases.

Path.is_char_device()

   Return "True" if the path points to a character device. "False"
   will be returned if the path is invalid, inaccessible or missing,
   or if it points to something other than a character device. Use
   "Path.stat()" to distinguish between these cases.

Path.samefile(other_path)

   Return whether this path points to the same file as *other_path*,
   which can be either a Path object, or a string.  The semantics are
   similar to "os.path.samefile()" and "os.path.samestat()".

   An "OSError" can be raised if either file cannot be accessed for
   some reason.

      >>> p = Path('spam')
      >>> q = Path('eggs')
      >>> p.samefile(q)
      False
      >>> p.samefile('spam')
      True

   Added in version 3.5.


Reading and writing files
-------------------------

Path.open(mode='r', buffering=-1, encoding=None, errors=None, newline=None)

   Open the file pointed to by the path, like the built-in "open()"
   function does:

      >>> p = Path('setup.py')
      >>> with p.open() as f:
      ...     f.readline()
      ...
      '#!/usr/bin/env python3\n'

Path.read_text(encoding=None, errors=None, newline=None)

   Return the decoded contents of the pointed-to file as a string:

      >>> p = Path('my_text_file')
      >>> p.write_text('Text file contents')
      18
      >>> p.read_text()
      'Text file contents'

   The file is opened and then closed. The optional parameters have
   the same meaning as in "open()".

   Added in version 3.5.

   Changed in version 3.13: The *newline* parameter was added.

Path.read_bytes()

   Return the binary contents of the pointed-to file as a bytes
   object:

      >>> p = Path('my_binary_file')
      >>> p.write_bytes(b'Binary file contents')
      20
      >>> p.read_bytes()
      b'Binary file contents'

   Added in version 3.5.

Path.write_text(data, encoding=None, errors=None, newline=None)

   Open the file pointed to in text mode, write *data* to it, and
   close the file:

      >>> p = Path('my_text_file')
      >>> p.write_text('Text file contents')
      18
      >>> p.read_text()
      'Text file contents'

   An existing file of the same name is overwritten. The optional
   parameters have the same meaning as in "open()".

   Added in version 3.5.

   Changed in version 3.10: The *newline* parameter was added.

Path.write_bytes(data)

   Open the file pointed to in bytes mode, write *data* to it, and
   close the file:

      >>> p = Path('my_binary_file')
      >>> p.write_bytes(b'Binary file contents')
      20
      >>> p.read_bytes()
      b'Binary file contents'

   An existing file of the same name is overwritten.

   Added in version 3.5.


Reading directories
-------------------

Path.iterdir()

   When the path points to a directory, yield path objects of the
   directory contents:

      >>> p = Path('docs')
      >>> for child in p.iterdir(): child
      ...
      PosixPath('docs/conf.py')
      PosixPath('docs/_templates')
      PosixPath('docs/make.bat')
      PosixPath('docs/index.rst')
      PosixPath('docs/_build')
      PosixPath('docs/_static')
      PosixPath('docs/Makefile')

   The children are yielded in arbitrary order, and the special
   entries "'.'" and "'..'" are not included.  If a file is removed
   from or added to the directory after creating the iterator, it is
   unspecified whether a path object for that file is included.

   If the path is not a directory or otherwise inaccessible, "OSError"
   is raised.

Path.glob(pattern, *, case_sensitive=None, recurse_symlinks=False)

   Glob the given relative *pattern* in the directory represented by
   this path, yielding all matching files (of any kind):

      >>> sorted(Path('.').glob('*.py'))
      [PosixPath('pathlib.py'), PosixPath('setup.py'), PosixPath('test_pathlib.py')]
      >>> sorted(Path('.').glob('*/*.py'))
      [PosixPath('docs/conf.py')]
      >>> sorted(Path('.').glob('**/*.py'))
      [PosixPath('build/lib/pathlib.py'),
       PosixPath('docs/conf.py'),
       PosixPath('pathlib.py'),
       PosixPath('setup.py'),
       PosixPath('test_pathlib.py')]

   See also: Pattern language documentation.

   By default, or when the *case_sensitive* keyword-only argument is
   set to "None", this method matches paths using platform-specific
   casing rules: typically, case-sensitive on POSIX, and case-
   insensitive on Windows. Set *case_sensitive* to "True" or "False"
   to override this behaviour.

   By default, or when the *recurse_symlinks* keyword-only argument is
   set to "False", this method follows symlinks except when expanding
   ""**"" wildcards. Set *recurse_symlinks* to "True" to always follow
   symlinks.

   Raises an auditing event "pathlib.Path.glob" with arguments "self",
   "pattern".

   Changed in version 3.12: The *case_sensitive* parameter was added.

   Changed in version 3.13: The *recurse_symlinks* parameter was
   added.

   Changed in version 3.13: The *pattern* parameter accepts a *path-
   like object*.

   Changed in version 3.13: Any "OSError" exceptions raised from
   scanning the filesystem are suppressed. In previous versions, such
   exceptions are suppressed in many cases, but not all.

Path.rglob(pattern, *, case_sensitive=None, recurse_symlinks=False)

   Glob the given relative *pattern* recursively.  This is like
   calling "Path.glob()" with ""**/"" added in front of the *pattern*.

   See also: Pattern language and "Path.glob()" documentation.

   Raises an auditing event "pathlib.Path.rglob" with arguments
   "self", "pattern".

   Changed in version 3.12: The *case_sensitive* parameter was added.

   Changed in version 3.13: The *recurse_symlinks* parameter was
   added.

   Changed in version 3.13: The *pattern* parameter accepts a *path-
   like object*.

Path.walk(top_down=True, on_error=None, follow_symlinks=False)

   Generate the file names in a directory tree by walking the tree
   either top-down or bottom-up.

   For each directory in the directory tree rooted at *self*
   (including *self* but excluding '.' and '..'), the method yields a
   3-tuple of "(dirpath, dirnames, filenames)".

   *dirpath* is a "Path" to the directory currently being walked,
   *dirnames* is a list of strings for the names of subdirectories in
   *dirpath* (excluding "'.'" and "'..'"), and *filenames* is a list
   of strings for the names of the non-directory files in *dirpath*.
   To get a full path (which begins with *self*) to a file or
   directory in *dirpath*, do "dirpath / name". Whether or not the
   lists are sorted is file system-dependent.

   If the optional argument *top_down* is true (which is the default),
   the triple for a directory is generated before the triples for any
   of its subdirectories (directories are walked top-down).  If
   *top_down* is false, the triple for a directory is generated after
   the triples for all of its subdirectories (directories are walked
   bottom-up). No matter the value of *top_down*, the list of
   subdirectories is retrieved before the triples for the directory
   and its subdirectories are walked.

   When *top_down* is true, the caller can modify the *dirnames* list
   in-place (for example, using "del" or slice assignment), and
   "Path.walk()" will only recurse into the subdirectories whose names
   remain in *dirnames*. This can be used to prune the search, or to
   impose a specific order of visiting, or even to inform
   "Path.walk()" about directories the caller creates or renames
   before it resumes "Path.walk()" again. Modifying *dirnames* when
   *top_down* is false has no effect on the behavior of "Path.walk()"
   since the directories in *dirnames* have already been generated by
   the time *dirnames* is yielded to the caller.

   By default, errors from "os.scandir()" are ignored.  If the
   optional argument *on_error* is specified, it should be a callable;
   it will be called with one argument, an "OSError" instance. The
   callable can handle the error to continue the walk or re-raise it
   to stop the walk. Note that the filename is available as the
   "filename" attribute of the exception object.

   By default, "Path.walk()" does not follow symbolic links, and
   instead adds them to the *filenames* list. Set *follow_symlinks* to
   true to resolve symlinks and place them in *dirnames* and
   *filenames* as appropriate for their targets, and consequently
   visit directories pointed to by symlinks (where supported).

   Note:

     Be aware that setting *follow_symlinks* to true can lead to
     infinite recursion if a link points to a parent directory of
     itself. "Path.walk()" does not keep track of the directories it
     has already visited.

   Note:

     "Path.walk()" assumes the directories it walks are not modified
     during execution. For example, if a directory from *dirnames* has
     been replaced with a symlink and *follow_symlinks* is false,
     "Path.walk()" will still try to descend into it. To prevent such
     behavior, remove directories from *dirnames* as appropriate.

   Note:

     Unlike "os.walk()", "Path.walk()" lists symlinks to directories
     in *filenames* if *follow_symlinks* is false.

   This example displays the number of bytes used by all files in each
   directory, while ignoring "__pycache__" directories:

      from pathlib import Path
      for root, dirs, files in Path("cpython/Lib/concurrent").walk(on_error=print):
        print(
            root,
            "consumes",
            sum((root / file).stat().st_size for file in files),
            "bytes in",
            len(files),
            "non-directory files"
        )
        if '__pycache__' in dirs:
              dirs.remove('__pycache__')

   This next example is a simple implementation of "shutil.rmtree()".
   Walking the tree bottom-up is essential as "rmdir()" doesn't allow
   deleting a directory before it is empty:

      # Delete everything reachable from the directory "top".
      # CAUTION:  This is dangerous! For example, if top == Path('/'),
      # it could delete all of your files.
      for root, dirs, files in top.walk(top_down=False):
          for name in files:
              (root / name).unlink()
          for name in dirs:
              (root / name).rmdir()

   Added in version 3.12.


Creating files and directories
------------------------------

Path.touch(mode=0o666, exist_ok=True)

   Create a file at this given path.  If *mode* is given, it is
   combined with the process's "umask" value to determine the file
   mode and access flags.  If the file already exists, the function
   succeeds when *exist_ok* is true (and its modification time is
   updated to the current time), otherwise "FileExistsError" is
   raised.

   See also:

     The "open()", "write_text()" and "write_bytes()" methods are
     often used to create files.

Path.mkdir(mode=0o777, parents=False, exist_ok=False)

   Create a new directory at this given path.  If *mode* is given, it
   is combined with the process's "umask" value to determine the file
   mode and access flags.  If the path already exists,
   "FileExistsError" is raised.

   If *parents* is true, any missing parents of this path are created
   as needed; they are created with the default permissions without
   taking *mode* into account (mimicking the POSIX "mkdir -p"
   command).

   If *parents* is false (the default), a missing parent raises
   "FileNotFoundError".

   If *exist_ok* is false (the default), "FileExistsError" is raised
   if the target directory already exists.

   If *exist_ok* is true, "FileExistsError" will not be raised unless
   the given path already exists in the file system and is not a
   directory (same behavior as the POSIX "mkdir -p" command).

   Changed in version 3.5: The *exist_ok* parameter was added.

Path.symlink_to(target, target_is_directory=False)

   Make this path a symbolic link pointing to *target*.

   On Windows, a symlink represents either a file or a directory, and
   does not morph to the target dynamically.  If the target is
   present, the type of the symlink will be created to match.
   Otherwise, the symlink will be created as a directory if
   *target_is_directory* is true or a file symlink (the default)
   otherwise.  On non-Windows platforms, *target_is_directory* is
   ignored.

      >>> p = Path('mylink')
      >>> p.symlink_to('setup.py')
      >>> p.resolve()
      PosixPath('/home/antoine/pathlib/setup.py')
      >>> p.stat().st_size
      956
      >>> p.lstat().st_size
      8

   Note:

     The order of arguments (link, target) is the reverse of
     "os.symlink()"'s.

   Changed in version 3.13: Raises "UnsupportedOperation" if
   "os.symlink()" is not available. In previous versions,
   "NotImplementedError" was raised.

Path.hardlink_to(target)

   Make this path a hard link to the same file as *target*.

   Note:

     The order of arguments (link, target) is the reverse of
     "os.link()"'s.

   Added in version 3.10.

   Changed in version 3.13: Raises "UnsupportedOperation" if
   "os.link()" is not available. In previous versions,
   "NotImplementedError" was raised.


Copying, moving and deleting
----------------------------

Path.copy(target, *, follow_symlinks=True, dirs_exist_ok=False, preserve_metadata=False)

   Copy this file or directory tree to the given *target*, and return
   a new "Path" instance pointing to *target*.

   If the source is a file, the target will be replaced if it is an
   existing file. If the source is a symlink and *follow_symlinks* is
   true (the default), the symlink's target is copied. Otherwise, the
   symlink is recreated at the destination.

   If the source is a directory and *dirs_exist_ok* is false (the
   default), a "FileExistsError" is raised if the target is an
   existing directory. If *dirs_exists_ok* is true, the copying
   operation will overwrite existing files within the destination tree
   with corresponding files from the source tree.

   If *preserve_metadata* is false (the default), only directory
   structures and file data are guaranteed to be copied. Set
   *preserve_metadata* to true to ensure that file and directory
   permissions, flags, last access and modification times, and
   extended attributes are copied where supported. This argument has
   no effect when copying files on Windows (where metadata is always
   preserved).

   Added in version 3.14.0a0 (unreleased).

Path.copy_into(target_dir, *, follow_symlinks=True, dirs_exist_ok=False, preserve_metadata=False)

   Copy this file or directory tree into the given *target_dir*, which
   should be an existing directory. Other arguments are handled
   identically to "Path.copy()". Returns a new "Path" instance
   pointing to the copy.

   Added in version 3.14.0a0 (unreleased).

Path.rename(target)

   Rename this file or directory to the given *target*, and return a
   new "Path" instance pointing to *target*.  On Unix, if *target*
   exists and is a file, it will be replaced silently if the user has
   permission. On Windows, if *target* exists, "FileExistsError" will
   be raised. *target* can be either a string or another path object:

      >>> p = Path('foo')
      >>> p.open('w').write('some text')
      9
      >>> target = Path('bar')
      >>> p.rename(target)
      PosixPath('bar')
      >>> target.open().read()
      'some text'

   The target path may be absolute or relative. Relative paths are
   interpreted relative to the current working directory, *not* the
   directory of the "Path" object.

   It is implemented in terms of "os.rename()" and gives the same
   guarantees.

   Changed in version 3.8: Added return value, return the new "Path"
   instance.

Path.replace(target)

   Rename this file or directory to the given *target*, and return a
   new "Path" instance pointing to *target*.  If *target* points to an
   existing file or empty directory, it will be unconditionally
   replaced.

   The target path may be absolute or relative. Relative paths are
   interpreted relative to the current working directory, *not* the
   directory of the "Path" object.

   Changed in version 3.8: Added return value, return the new "Path"
   instance.

Path.move(target)

   Move this file or directory tree to the given *target*, and return
   a new "Path" instance pointing to *target*.

   If the *target* doesn't exist it will be created. If both this path
   and the *target* are existing files, then the target is
   overwritten. If both paths point to the same file or directory, or
   the *target* is a non-empty directory, then "OSError" is raised.

   If both paths are on the same filesystem, the move is performed
   with "os.replace()". Otherwise, this path is copied (preserving
   metadata and symlinks) and then deleted.

   Added in version 3.14.

Path.move_into(target_dir)

   Move this file or directory tree into the given *target_dir*, which
   should be an existing directory. Returns a new "Path" instance
   pointing to the moved path.

   Added in version 3.14.

Path.unlink(missing_ok=False)

   Remove this file or symbolic link.  If the path points to a
   directory, use "Path.rmdir()" instead.

   If *missing_ok* is false (the default), "FileNotFoundError" is
   raised if the path does not exist.

   If *missing_ok* is true, "FileNotFoundError" exceptions will be
   ignored (same behavior as the POSIX "rm -f" command).

   Changed in version 3.8: The *missing_ok* parameter was added.

Path.rmdir()

   Remove this directory.  The directory must be empty.


Permissions and ownership
-------------------------

Path.owner(*, follow_symlinks=True)

   Return the name of the user owning the file. "KeyError" is raised
   if the file's user identifier (UID) isn't found in the system
   database.

   This method normally follows symlinks; to get the owner of the
   symlink, add the argument "follow_symlinks=False".

   Changed in version 3.13: Raises "UnsupportedOperation" if the "pwd"
   module is not available. In earlier versions, "NotImplementedError"
   was raised.

   Changed in version 3.13: The *follow_symlinks* parameter was added.

Path.group(*, follow_symlinks=True)

   Return the name of the group owning the file. "KeyError" is raised
   if the file's group identifier (GID) isn't found in the system
   database.

   This method normally follows symlinks; to get the group of the
   symlink, add the argument "follow_symlinks=False".

   Changed in version 3.13: Raises "UnsupportedOperation" if the "grp"
   module is not available. In earlier versions, "NotImplementedError"
   was raised.

   Changed in version 3.13: The *follow_symlinks* parameter was added.

Path.chmod(mode, *, follow_symlinks=True)

   Change the file mode and permissions, like "os.chmod()".

   This method normally follows symlinks. Some Unix flavours support
   changing permissions on the symlink itself; on these platforms you
   may add the argument "follow_symlinks=False", or use "lchmod()".

      >>> p = Path('setup.py')
      >>> p.stat().st_mode
      33277
      >>> p.chmod(0o444)
      >>> p.stat().st_mode
      33060

   Changed in version 3.10: The *follow_symlinks* parameter was added.

Path.lchmod(mode)

   Like "Path.chmod()" but, if the path points to a symbolic link, the
   symbolic link's mode is changed rather than its target's.


Pattern language
================

The following wildcards are supported in patterns for "full_match()",
"glob()" and "rglob()":

"**" (entire segment)
   Matches any number of file or directory segments, including zero.

"*" (entire segment)
   Matches one file or directory segment.

"*" (part of a segment)
   Matches any number of non-separator characters, including zero.

"?"
   Matches one non-separator character.

"[seq]"
   Matches one character in *seq*.

"[!seq]"
   Matches one character not in *seq*.

For a literal match, wrap the meta-characters in brackets. For
example, ""[?]"" matches the character ""?"".

The ""**"" wildcard enables recursive globbing. A few examples:

+---------------------------+-----------------------------------------------------------------------+
| Pattern                   | Meaning                                                               |
|===========================|=======================================================================|
| ""**/*""                  | Any path with at least one segment.                                   |
+---------------------------+-----------------------------------------------------------------------+
| ""**/*.py""               | Any path with a final segment ending "".py"".                         |
+---------------------------+-----------------------------------------------------------------------+
| ""assets/**""             | Any path starting with ""assets/"".                                   |
+---------------------------+-----------------------------------------------------------------------+
| ""assets/**/*""           | Any path starting with ""assets/"", excluding ""assets/"" itself.     |
+---------------------------+-----------------------------------------------------------------------+

Note:

  Globbing with the ""**"" wildcard visits every directory in the
  tree. Large directory trees may take a long time to search.

Changed in version 3.13: Globbing with a pattern that ends with ""**""
returns both files and directories. In previous versions, only
directories were returned.

In "Path.glob()" and "rglob()", a trailing slash may be added to the
pattern to match only directories.

Changed in version 3.11: Globbing with a pattern that ends with a
pathname components separator ("sep" or "altsep") returns only
directories.


Comparison to the "glob" module
===============================

The patterns accepted and results generated by "Path.glob()" and
"Path.rglob()" differ slightly from those by the "glob" module:

1. Files beginning with a dot are not special in pathlib. This is like
   passing "include_hidden=True" to "glob.glob()".

2. ""**"" pattern components are always recursive in pathlib. This is
   like passing "recursive=True" to "glob.glob()".

3. ""**"" pattern components do not follow symlinks by default in
   pathlib. This behaviour has no equivalent in "glob.glob()", but you
   can pass "recurse_symlinks=True" to "Path.glob()" for compatible
   behaviour.

4. Like all "PurePath" and "Path" objects, the values returned from
   "Path.glob()" and "Path.rglob()" don't include trailing slashes.

5. The values returned from pathlib's "path.glob()" and "path.rglob()"
   include the *path* as a prefix, unlike the results of
   "glob.glob(root_dir=path)".

6. The values returned from pathlib's "path.glob()" and "path.rglob()"
   may include *path* itself, for example when globbing ""**"",
   whereas the results of "glob.glob(root_dir=path)" never include an
   empty string that would correspond to *path*.


Comparison to the "os" and "os.path" modules
============================================

pathlib implements path operations using "PurePath" and "Path"
objects, and so it's said to be *object-oriented*. On the other hand,
the "os" and "os.path" modules supply functions that work with low-
level "str" and "bytes" objects, which is a more *procedural*
approach. Some users consider the object-oriented style to be more
readable.

Many functions in "os" and "os.path" support "bytes" paths and paths
relative to directory descriptors. These features aren't available in
pathlib.

Python's "str" and "bytes" types, and portions of the "os" and
"os.path" modules, are written in C and are very speedy. pathlib is
written in pure Python and is often slower, but rarely slow enough to
matter.

pathlib's path normalization is slightly more opinionated and
consistent than "os.path". For example, whereas "os.path.abspath()"
eliminates "".."" segments from a path, which may change its meaning
if symlinks are involved, "Path.absolute()" preserves these segments
for greater safety.

pathlib's path normalization may render it unsuitable for some
applications:

1. pathlib normalizes "Path("my_folder/")" to "Path("my_folder")",
   which changes a path's meaning when supplied to various operating
   system APIs and command-line utilities. Specifically, the absence
   of a trailing separator may allow the path to be resolved as either
   a file or directory, rather than a directory only.

2. pathlib normalizes "Path("./my_program")" to "Path("my_program")",
   which changes a path's meaning when used as an executable search
   path, such as in a shell or when spawning a child process.
   Specifically, the absence of a separator in the path may force it
   to be looked up in "PATH" rather than the current directory.

As a consequence of these differences, pathlib is not a drop-in
replacement for "os.path".

-[ Footnotes ]-

[1] "os.path.relpath()" calls "abspath()" to make paths absolute and
    remove "".."" parts, whereas "PurePath.relative_to()" is a lexical
    operation that raises "ValueError" when its inputs' anchors differ
    (e.g. if one path is absolute and the other relative.)

[2] "os.path.expanduser()" returns the path unchanged if the home
    directory can't be resolved, whereas "Path.expanduser()" raises
    "RuntimeError".

[3] "os.path.abspath()" removes "".."" components without resolving
    symlinks, which may change the meaning of the path, whereas
    "Path.absolute()" leaves any "".."" components in the path.

[4] "os.walk()" always follows symlinks when categorizing paths into
    *dirnames* and *filenames*, whereas "Path.walk()" categorizes all
    symlinks into *filenames* when *follow_symlinks* is false (the
    default.)
