This is probably NOT the best solution, but here's how you can "peek" at 
the main module. In myFunc1 put:

import sys
main = sys.modules['__main__']
print main.a

You can do anything you want with main.a (as long as its legal in Python).

This technique also lets you reference anything in any imported module.
