Tools such as ruff can ignore "imported but unused" warnings if a
line ends with "# noqa: F401". It avoids the temptation to remove
an import which is used effectively.
It creates a modified copy of an object by calling the object's
__replace__() method.
It is a generalization of dataclasses.replace(), named tuple's _replace()
method and replace() methods in various classes, and supports all these
stdlib classes.
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.
* 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.
This commit reverts commit ac0333e1e1 as the original links are working again and they provide extended features such as comments and alternative versions.
Added str.removeprefix and str.removesuffix methods and corresponding
bytes, bytearray, and collections.UserString methods to remove affixes
from a string if present. See PEP 616 for a full description.
