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
