Thanks for your suggestions Chris and Terry. The answer I was looking for is the modulefinder module which is part of the standard lib. Works like a charm!
Quote: This module provides a ModuleFinder class that can be used to determine the set of modules imported by a script. modulefinder.py can also be run as a script, giving the filename of a Python script as its argument, after which a report of the imported modules will be printed. https://docs.python.org/3.5/library/modulefinder.html Note there's a similar module for Python 2.7. -- Malcolm -- https://mail.python.org/mailman/listinfo/python-list
