That's what happens when you do "from variables import *", it creates
those names in the local namespace. If you just import the module,
then you can do what you want. For example:
---variables.py---
myvar = 5
print myvar
---foo.py---
import variables
def PrintVar():
print variables.myvar
---bar.py---
import variables, foo
print variables.myvar
variables.myvar = 2
print variables.myvar
foo.PrintVar()
---output from running bar.py---
5
5
2
2
For more on how the import statement works, see the library reference
(http://docs.python.org/ref/import.html), or maybe this article on the
various ways you can import things and the differences between them
