[New-bugs-announce] [issue46122] Update/fix types.UnionType to types.Union in Built-in Types documentation

[Vivek Vashist]

New submission from Vivek Vashist <vivekvashist at gmail.com>:

There is an error in https://docs.python.org/3/library/stdtypes.html#types-union example.

Looks like there is no types.UnionType

BROKEN:

>>> import types
>>> isinstance(int | str, types.UnionType)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'types' has no attribute 'UnionType'. Did you mean: 'FunctionType'?
>>> [att for att in dir(types) if 'Union' in att]
['Union']
>>>

WORKING:

>>> import types
>>>
>>> isinstance(int | str, types.Union)
True
>>>

I'll raise a PR shortly.
