add ${workspaceFolder} to "PYTHONPATH" in launch.json by default

[Akopov4]

Hi, I'm new User of VScode. Previously I used Jetbrains Pycharm and not for a long time ago switched to VSCode.
Please add
"env": {
"PYTHONPATH": "${workspaceFolder};${env:PYTHONPATH}"
}
as default configuration parameters, when create to launch.json
Pycharm did it for a long time ago
Thank you in advance

Thanks for the issue. Pylance doesn't actually handle debugging of Python code. Transferring.

@Akopov4 You see an issue when you run or you see it with handling of imports in the editor?

[Akopov4]

it's not an issue, it's feature request

"env": {
"PYTHONPATH": "${workspaceFolder}"
}

without it, when a user tries to run python file in debugger, import statement rooted from workspace root won't be resolved at runtime even if it is resolved at editing time due to our import resolve heuristic.

root/
        lib/
             __init__.py
             module.py
             currentfile.py

currentfile.py
import module # this will work at runtime and edit time
import lib.module # this won't work at runtime but will work at edit time.

user might want it to just work when debugging?

that said, if user run currentfile.py from terminal, it still won't work unless user add root to sys.path in some ways such as setting PYTHONPATH env var or sys.path.append(...) from code.

user could use .env for it to be set on terminal but when user run it in regular command line it won't work again.

but it will at least make it to just work for debugger?

maybe "PYTHONPATH": "${workspaceFolder};${env:PYTHONPATH}", would be better for reason that there were already PYTHONPATH environmental variable set

@heejaechang usually directories like .vscode, .idea and so on are included in gitignore file. So they don't affect production codes. This configuration is used by debugger and by "Run python file" in the editor. Soultion of @V4n1sh is better then my one
