Python: How can I use variable from main file in module?

Question

I have 2 files main.py and irc.py.
main.py

import irc
var = 1
func()

irc.py

def func():
    print var

Answer 1

Well, that's my code which works fine:

func.py:

import __main__
def func():
    print(__main__.var)

main.py:

from func import func

var="It works!"
func()
var="Now it changes!"
func()
