UP043

UP043
Python 3.13 introduced the ability for type parameters to specify default values. As such, the default type arguments for some types in the standard library (e.g., Generator, AsyncGenerator) are now optional.
Omitting type parameters that match the default values can make the code more concise and easier to read.

Generator[int, None, None] -> Generator[int]

issue

Currently, UP043 only applies to typing.Generator, but it should also support collections.abc.Generator.

Example

from collections.abc import Generator
from typing import Generator as tG

a = Generator[int, None, None] # No warns
b = tG[int, None, None]  # UP043
