When you run "python w.py" the *script* w.py is loaded as the module __main__. Importing a module called 'w' creates a new module which is unrelated to __main__. If you want access to variables defined in the main script then you need to import __main__. Don't use 'from module import *': The import statements are executed when the interpreter reaches them in the source. Even if you fix your code to import from __main__, the values you try to import from __main__ won't exist when the import statement executes: the first 'from a import *' will load and execute all of module 'a', but when that executes 'from __main__ import *' it just imports names defined in the main script *before* a was imported. In general, don't try to do this: put all your classes into modules and just put minimal startup code into a script. -- http://mail.python.org/mailman/listinfo/python-list
