That is by design and IMO a good thing as you don't need to declare things(the '=' sort of done it for you) in python. I think you can do something like globals()['s'] but that is ugly and should be discouraged. Just use a mutable object like s=[1] or a Ref class or whatever similar implementation if you need this "shared write" functionality. Just reading is perfectly fine. -- http://mail.python.org/mailman/listinfo/python-list
