||||
``Union[int, str]`` multiple times would return the same object
|
||||
(``Union[int, str] is Union[int, str]`` would be ``True``), but now it will
|
||||
return two different objects. Users should use ``==`` to compare unions for equality, not
|
||||
``is``. New-style unions have never been cached this way.
|
||||
This change could increase memory usage for some programs that use a large number of
|
||||
unions created by subscripting ``typing.Union``. However, several factors offset this cost:
|
||||
unions used in annotations are no longer evaluated by default in Python 3.14
|
||||
because of :pep:`649`; an instance of :class:`types.UnionType` is
|
||||
itself much smaller than the object returned by ``Union[]`` was on prior Python
|
||||
versions; and removing the cache also saves some space. It is therefore
|
||||
unlikely that this change will cause a significant increase in memory usage for most
|
||||
users.
|
||||
- Both syntaxes for creating a union now produce the same string
|
||||
representation in :func:`repr`.
|
||||
For example, ``repr(Union[int, str])`` is now ``"int | str"`` instead of
|
||||
``"typing.Union[int, str]"``.
|
||||
|
||||
- Unions created using the old syntax are no longer cached.
|
||||
Previously, running ``Union[int, str]`` multiple times would return
|
||||
the same object (``Union[int, str] is Union[int, str]`` would be ``True``),
|
||||
but now it will return two different objects.

|

|

- Previously, old-style unions were implemented using the private class
|
||||
``typing._UnionGenericAlias``. This class is no longer needed for the implementation,
|
||||
but it has been retained for backward compatibility, with removal scheduled for Python
|
||||
3.17. Users should use documented introspection helpers like :func:`typing.get_origin`
|
||||
and :func:`typing.get_args` instead of relying on private implementation details.
|
||||
- It is now possible to use :class:`typing.Union` itself in :func:`isinstance` checks.
|
||||
For example, ``isinstance(int | str, typing.Union)`` will return ``True``; previously
|
||||
this raised :exc:`TypeError`.
|
||||
- The ``__args__`` attribute of :class:`typing.Union` objects is no longer writable.
|
||||
- It is no longer possible to set any attributes on :class:`typing.Union` objects.
