[Tutor] variables question.

[Luke Paireepinart]

It's pretty typical for scoping rules. If you define variables outside of your funcs you can access them inside the func. If you want to change the value in the function you need to declare the scope as global. If you make another variable with the same name inside of a function it will shadow the outer variable. You could define the variables in a parent script if you want. This is actually how imports work basically.

In config.py
foo = "bar"

In your py
from config import foo
def bar():
    print foo
