I cannot replicate this (with pandera 0.18.0 and pandas 2.2.0), so I guess it is not related to pandera but to your environment and VS Code setup.

@schatimo That's somehow reassuring. What language server are you using, I'm on pylance but I've read mypy is better integrated?

Also, I'm not getting column suggestions:

And the infered type is unknown:

Is it behaving like this in your setup?

I'm on the same librairy version too, so it's definitely a VSCode setup thing: pandas==2.2.0 pandera==0.18.0

Do you have additionnal editor settings?

[schatimo]

I use Pylance, yes, but mypy for static type checking (as I do not use pyright which comes with Pylance but is disabled by default if I recall correctly). I have a couple of settings in VS Code. So, I would close the issue as it is unrelated to pandera and not a bug but related to your settings.

Go ahead, but I'd love to get some more directions on how to enable those type hints properly
