How do I create a text file from the selected objects containing name and collection?

Question

I'm trying to do something similar as in this post, but instead of all dimensions from each object I want to know to which collection they belong.

The part of the code I changed was:

selection = bpy.context.selected_objects
iterate through the selected objects
for sel in selection:
    # get collection to which the object belongs
    col = bpy.context.collection
    # write the selected object's name and dimensions to a string
    result += "%s, %s" % (sel.name, col.name)

However, this seems to loop over the collections that are inside of the selected objects instead of the other way around. How do I change my code to see the collection the objects belongs to?

Answer 1

check this out:

import bpy
for eachCol in bpy.data.collections:
print("Collection:", eachCol.name)

for eachObject in eachCol.objects:

    print("  ", eachObject.name)

Test result:

or if you only want the info about the selected objects:

import bpy
selected = bpy.context.selected_objects
for eachSel in selected:
for eachCol in bpy.data.collections:
    for eachObject in eachCol.objects:

        if eachObject == eachSel:

            print(eachObject.name, "is in", eachCol.name)

test result:
