What Guillaume C. meant is:
To make a variable that is assigned within a function global you have to
declare it global
def foo():
global x
x = 42
foo()
print x
but that having many of these globals is a bad design and you should
use instance attributes instead:
class A(object):
def foo(self):
self.x = 42
a = A()
a.foo()
print a.x
Personally, I often prefer
def foo():
return 42
x = foo()
print x
which is both explicit and concise.
These are basic considerations in Python, so I suggest that you read an
introductory text on the language before you proceed with your endeavours.
