Bug Report / Documentation
On the documentation for typing.MappingView and typing.ItemsView, it states that we should have:
import typing
assert issubclass(typing.MappingView, typing.Iterable)
assert issubclass(typing.MappingView, typing.Sized)when in fact we actually have:
import collections.abc
import typing
assert typing.MappingView.mro() == [collections.abc.MappingView, collections.abc.Sized, object]and similarly, we actually have:
import typing
assert issubclass(typing.ItemsView, typing.AbstractSet)for python >= 3.7 on the versions I tried (3.7.9, 3.8.5, 3.9.5, and 3.10.0). On python = 3.5.4 and python = 3.6.8, I get the types for typing.MappingView consistent with the documentation, but inconsistent types for typing.ItemsView.
