If this question is about the problem from the previous question asked by you earlier today then the problem is circular import. Please learn about possible solutions from already answered questions - stackoverflow.com/search?q=python%20circular%20import. — Poolka

if you have two files at the same directory, you can simply import one file to the other:

test1.py:

a = 5
b = 10

test2.py:

import test1

print test1.a
print test1.b

or:

from test1 import a,b
print a
print b
