Your function in sc2 is not returning anything. So you are not getting any output in sc1. include a return statement in main.

sc1.py

import sys import os import sc2 os.system ('python sc2.py') varB = sc2.main("Hello") #sc1 doesn't know varA print(varB)

sc2.py

def main(_argv): varA = _argv return varA # in order to actually return varA if __name__ == '__main__': try: app.run(main) except SystemExit: pass

Two points:

You can't use varA in sc1.py, because sc1.py doesn't know it. It's defined in sc2.py
You have to literally use the keyword return and whatever you want to return so that that value will be returned by sc2.py's main function and stored in varB.
