Yes. Your error is that you are looking at global variables as "a way to share data between modules". The advice is "Don't do that". Limited use of global variables whose values are updated is barely tolerable within a single module that will be executed by a single thread of a single process. Otherwise you can end up with monstrosities like database "forms" applications with hundreds of globals. Google for concepts like "modularity" and "information hiding". Then read about OOP. -- http://mail.python.org/mailman/listinfo/python-list
