How can I tell which module/script has just run this script in Python?

How can I tell which module/script has just run this script in Python?

Problem Description:

I have a module called detector.py, and I want to import the module Vimba into it only if detector.py is being imported by experiment.py. Is this importer-specific conditional importing possible?

If I import this module (detector.py) into a different module, say test.py, I don’t want to try to import Vimba.

I’ve tried checking __name__ to see if it tells me who my importer is, but I only get the general module path of this module project.detection.detector.

You can use sys.modules to check if a module has been imported.

import sys

if 'experiment' in sys.modules:
    import Vimba
