As a workaround, you could consider setting environment variables in the outer layer, like this.

main.py:

import os
os.environ['MYVAL'] = str(myintvariable)

mymodule.py:

import os

myval = None
if 'MYVAL' in os.environ:
    myval = os.environ['MYVAL']

As an extra precaution, handle the case when MYVAL is not defined inside the module.
