bpo-26579: Add object.getstate(). (GH-2821)

2022-04-06T17:00:14+00:00

Copying and pickling instances of subclasses of builtin types
bytearray, set, frozenset, collections.OrderedDict, collections.deque,
weakref.WeakSet, and datetime.tzinfo now copies and pickles instance attributes
implemented as slots.

Fix minor details in the Counter docs (GH-31029)

2022-02-02T04:18:11+00:00

Minor code rearrangement to group related methods together. (GH-30813)

2022-01-23T00:47:22+00:00

* Make example more focused with math.prod()
* Move comparison tests to the multiset operations section

bpo-27275: Change popitem() and pop() methods of collections.OrderedDict (GH-27530)

2021-08-03T11:00:55+00:00

* Unify the C and Python implementations of OrderedDict.popitem().

The C implementation no longer calls ``__getitem__`` and ``__delitem__``
methods of the OrderedDict subclasses.

* Change popitem() and pop() methods of collections.OrderedDict

For consistency with dict both implementations (pure Python and C)
of these methods in OrderedDict no longer call __getitem__ and
__delitem__ methods of the OrderedDict subclasses.

Previously only the Python implementation of popitem() did not
call them.

collections module.
