Namespaces with Module Imports

Question

I am learning Python and am still a beginner, although I have been studying it for about a year now. I am trying to write a module of functions which is called within a main

Answer 1

As others have said, there isn't actually a global pi in your module1. A good solution for you is this, which only imports pi once from math and explicitly ensures that the pi you're getting is the one from module1:

main.py:

import module1

def wow():
    print module1.pi

wow()
module1.cool()

module1.py:

from math import pi

def cool():
    print pi
