How assign shortcut to custom function?

Question

i have this simple function in the Blender text editor :

import bpy
bpy.ops.object.select_pattern(pattern="Cube?")
bpy.ops.object.select_pattern(pattern="Sphere?")

I just simply want to run this function using a shortcut. How can i bind a shortcut to it ?

Thanks.

You would have to implement a custom Operator and add your code to its execute method:

class OBJECT_OT_CustomOp(bpy.types.Operator):
    """Tooltip"""
    bl_idname = "object.simple_operator"
    bl_label = "Simple Object Operator"
def execute(self, context):

    # Your code here ...
    bpy.ops.object.select_pattern(pattern="Cube?")
    bpy.ops.object.select_pattern(pattern="Sphere?")

    return {'FINISHED'}

import bpy
bl_info = {
    "name": "Your Addon Name",

class OBJECT_OT_CustomOp(bpy.types.Operator):

    # Your code here ...
    bpy.ops.object.select_pattern(pattern="Cube?")
    bpy.ops.object.select_pattern(pattern="Sphere?")

    return {'FINISHED'}



addon_keymaps = []
def register():
    bpy.utils.register_class(OBJECT_OT_CustomOp)
# Add the hotkey
wm = bpy.context.window_manager
kc = wm.keyconfigs.addon
if kc:
    km = wm.keyconfigs.addon.keymaps.new(name='3D View', space_type='VIEW_3D')
    kmi = km.keymap_items.new(OBJECT_OT_CustomOp.bl_idname, type='W', value='PRESS', ctrl=True)
    addon_keymaps.append((km, kmi))



def unregister():
    bpy.utils.unregister_class(OBJECT_OT_CustomOp)
# Remove the hotkey
for km, kmi in addon_keymaps:
    km.keymap_items.remove(kmi)
addon_keymaps.clear()



if name == "main":
    register()

Assuming you're using >v2.8, this should work. Very basic and there might be a better way, (almost certainly!!) but it works. After you run this, a new menu item should show up in your "Select" menu. Right click this item and assign a shortcut as normal.

## Read the comments for a very basic explanation of what the various parts do

    bl_info = { ## stuff so Blender can find your code
    "name": "My Addon",
    "author": "Your Name",
    "version": (0, 1),
    "blender": (2, 90, 0),
    "location": "View3D > Select",
    "description": "Your addon descriptioin",
    "warning": "",
    "wiki_url": "",
    "category": "3D View",
    }
import bpy
from bpy.types import Operator
class MYADDON_OT_My_Class(Operator): ## stuff to be able to make a menu item
    bl_idname = "object.my_class"
    bl_label = "Test"
    bl_description = "My Description"
    bl_space_type = "VIEW_3D"
    bl_region_type = 'UI'
def invoke(self, context, event):
    ## the main event, this will be ran when your button is pressed
    bpy.ops.object.select_pattern(pattern="Cube?")
    bpy.ops.object.select_pattern(pattern="Sphere?")

    return {'FINISHED'}



def menu_func(self, context): ## creating the menu item
    self.layout.operator(MYADDON_OT_My_Class.bl_idname, icon='MESH_CUBE')
def register(): ## register the functions so Blender can use them
    bpy.utils.register_class(MYADDON_OT_My_Class)
    bpy.types.VIEW3D_MT_select_object.append(menu_func)
def unregister(): ## unregister when the addon is removed later
    bpy.utils.unregister_class(MYADDON_OT_My_Class)
    bpy.types.VIEW3D_MT_select_object.remove(menu_func)
if name == "main":
    register()
