Running and linting Python from Docker without installing Python

[AJGranowski]

I think it could be neat to set the Python executable "path" to something like

docker run -it --rm --mount type=bind,source="$pwd",target=/vscode --workdir /vscode python:3 python 

so we could run Python projects without having Python locally installed.

Currently this does not work because VSCode will wrap the interpreter "path" with quotes

PS C:\docker-test> & "docker run -it --rm --mount type=bind,source="$pwd",target=/vscode --workdir /vscode python:3 python" c:/docker-test/src/main.py
