setting up the VS Code to work with Python - virtual environment-configuration

[snippsat]

i need to get a closer idea of the setting up VSCode for the work with Python:

VS Code from start
I always start for command line setting up virtual environment then code . to start VS Code.
Find automatically virtual environment and can use Code Runner eg Button.
So Code Runner always follow the selected interpreter down in left corner,as use setting "python": "$pythonPath $fullFileName",.

Quick tour.

E:\div_code
λ python -m venv forum_env

# Cd in
E:\div_code
λ cd forum_env\

# Activate environment 
E:\div_code\forum_env
λ E:\div_code\forum_env\Scripts\activate

# Start VS Code
(forum_env) E:\div_code\forum_env
λ code .
