How Do Scan A Script For Return Values From A Upper Script In Python?

import os import pdb os.system('ToBuildOrNot.py MSS_sims') for output in os.system: if ToBuildOrNot is True: print 'The MSS_sims Needs To rebuilt' elif ToBuil

Solution 1:

Don't invoke a Python script from a Python script by using system, which spawns a whole other interpreter. Just import it. Like this:

import ToBuildOrNot
needsBuild = ToBuildOrNot.run() # or whatever you call your top-level function

Since ToBuildOrNot.py is a script now, make sure the "main" function is protected so it doesn't execute automatically on import. Most people do it this way in Python: What does if __name__ == "__main__": do?
