[New-bugs-announce] [issue45776] abc submodule not an attribute of collections on Python 3.10.0 on Windows

[Steve Canny]

New submission from Steve Canny <stcanny at gmail.com>:

On CPython 3.10.0 on Windows but not MacOS, AttributeError is raised when referencing `abc` on collections (instead of importing `collections.abc`).

>>> import collections
>>> collections.abc.Container
AttributeError: module 'collections' has no attribute 'abc'

This works on MacOS CPython 3.10.0 and also works on Windows CPython 3.9.6.

It's possibly interesting this coincides with collection ABCs being made unavailable directly from `collections` with this 3.9 -> 3.10 version change, but that's just a guess, for whatever it's worth.
