how to tell if a script is running independently or called as subprocess in python

Question

I have two scripts, A.py and B.py let's call them. A is an independent script that can run on its own, but can also be run by calling it from B. B on the other hand needs A to complete. I need to include something in my A script so that a couple configurations can be altered depending on where it's being called from.

I'm calling A from B like this: subprocess.call("A")

What can I do to let A know that it was called from B?

Use command line arguments:

subprocess.call(["A", "--called-from-B"])

Do you mean add an arg to `A`? – Krin123 Jun 29 '15 at 22:08
