[FIXED] (Im)mutability of OrderedDict

Issue

Is Python's OrderedDict data structure a mutable collection?

The documentation does not say anything about it, and after a quick search on the web, I have not found any answer yet.

When in doubt regarding mutability of class you might run following test

from collections import OrderedDict
from collections.abc import MutableSequence, MutableSet, MutableMapping
print(issubclass(OrderedDict,(MutableSequence,MutableSet,MutableMapping)))

output

True

See Collections Abstract Base Classes in collections.abc docs for other things which can be checked this way.
