Just to be clear:

mod1.py:
a=5

------------------------
mod2.py:
import mod1

def testfunc1():
    print mod1.a

def testfunc2():
    mod1.a = 6

-------------------------
main.py:
import mod1
import mod2

mod2.testfunc1()
mod2.testfunc2()
mod2.testfunc1()

-----------------------

The main.py program will print out "5" and "6."

If I understand your original question, this example will demonstrate
it.  But I could have understood wrong!
