feat: add overload.

[ya7010]

Using the latest pylance, pa.Int, etc. will result in an error.

This is because Callable[[_DataTypeClass], _DataTypeClass]] can now be correctly parsed and Callable is now a function and not a class. Defining override avoids problems in many cases, such as pa.Int.

English Message is here.

Class is required, but received “_DataTypeClass[Unknown] | ((_DataTypeClass[Unknown]) -> _DataTypeClass[Unknown])”
  “(_DataTypeClass[Unknown]) -> _DataTypeClass[Unknown]” is not a class

Python 3.11.0 pylance v2024.9.2 pandas 2.2.2

thanks @yassun7010 ! please be sure to run the pre-commit checks: https://pandera.readthedocs.io/en/latest/CONTRIBUTING.html#set-up-pre-commit

[ya7010]

@cosmicBboy

OK!

pre-commit executed 🙇

[cosmicBboy]

@yassun7010 looks like linter is still complaining... can you try performing the lint on a python 3.11 environment?

[ya7010]

@cosmicBboy

Thank you!

It appears that pylint does not support overload.

This writing is correct as overload, and the warning was ignored by the comment.

[cosmicBboy]

@yassun7010 looks like the black linter is unhappy

[ya7010]

@cosmicBboy Sorry 🙏

I fiexed and run pre-commit run --all on Python 3.11.

[ya7010]

Seems to be a failure in uv installation.

This appears to be a separate issue from this fix.

thanks @yassun7010, and congrats on your first contribution to pandera! 🚀
