Excluding collections from view layer using script

Question

Hello Im working on really big project and I need to exclude all collections from layerand reverse using script I tried this

import bpy

coll = bpy.data.collections
for c in coll:
   c.exclude = False

But it doesnt seem to work, any ideas where it went wrong or how to solve my problem? Any help is appreciated.

You need to use refence from view_layer.layer_collection:

import bpy
   
vl_colls = bpy.context.view_layer.layer_collection.children

# toggle
for coll in vl_colls:
    coll.exclude = not coll.exclude

Layer collection vs Collection:

reference

• LayerCollection(bpy_struct)
• Collection(ID)

Properties of LayerCollection(bpy_struct):

• Exclude: .exclude
• Hide in Viewport: .hide_viewport
• Holdout: .holdout
• Indirect Only: .indirect_only

Accessed through bpy.context.view_layer.layer_collection.children

Properties of Collection(ID):

• Disable Selection: .hide_select
• Disable in Viewport: .hide_viewport
• Disable in Render: .hide_render

Accessed through bpy.data.collections
