Run Debug automaticly

well, as i saw, one of my friends, when he creates a .py document, the debbuger auto add its configuration to exec and run the actual .py file, but whenm i create on ei have to add manualy all the path where its located and choose the interpreter that i want.

how can i configure the app to autoadd this main.py (for example) when i create it on to the debug settings?
