some problems about vscode and python

[nikelin18]

Some options about 'Go' don't work ,like these

And my Pyhton files can not prompts for function information when mouse over the function name.

I just configured the system environment variables before the problem happened.

Do you have the Python extension installed? And what language server do you have selected?

[nikelin18]

Thanks, I have installed Python extension and selected "Jedi" . And these problems don't exist in my .C files.
Should I re install Python3.9?

[brettcannon]

Please try selecting "Pylance" as your language server and let us know if that solves the issue.
