Just guessing, but your problem likely lies in A.Function1 (the one
that sets global variables):
python does something kinda tricky with namespaces and global
variables: if you refer to the name of a global variable inside a
function, and only READ from it, then the name is bound to the global
variable, and it reads the global value. If, however, you ASSIGN to a
name which is the same as a global variable, then it actually creates
a new, local variable with the same name, and assigns to that - the
value stored in the global variable will not change.
To get around this, you need to explicitly declare the variable to to
be global in your function, like so:
# module A
myGlobal = "I'm not set!"
def setGlobal():
global myGlobal # bind myGlobal to the global A.myGlobal
myGlobal = "I'm all set!"
# Just to illustrate...
def printGlobal():
print myGlobal # This will work, because we haven't done any assignment
