What part don't you understand? This is Terry's template. It's not meant to work as-is, he has to fill in the details, such as what test_main() actually does. The "if __name__ == '__main__'" idiom is a common way of making a Python script. When you import a module, Python automatically adds a global to it called __name__, and sets it to the name of the module. E.g.: >>> import math >>> math.__name__ 'math' When you run a module as a script, Python sets the __name__ to '__main__' instead. So this is a (slightly hacky) way of distinguishing code that runs when the module is imported from code that runs on execution. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
