Unlike Python2's execfile this does not modify the current namespace by default. For that you have to explicitly pass in globals() & locals().
Many situations that you might think would naturally give rise to undefined variables, such as processing configuration files or web forms, are handled better by employing a dictionary and testing for the presence of a key (with the has_key method, a try / except, or the get or setdefault methods of dictionary objects).
