flake8-new-union-types
Flake8 plugin to enforce the new Union and Optional annotation syntax defined in PEP 604.
Union[X, Y] = X | Y
Optional[X] = X | None
Note that it's impossible to use forward references in the new syntax, like this:
"X" | int
such a case can be expressed as a string containing both union terms:
"X | int"
Installation
pip install flake8-new-union-types
or if you use poetry:
poetry add --dev flake8-new-union-types
