Everything (well, except statements and expressions...) in Python is an object, including classes, modules and functions, and Python objects are really 'dynamic', ie you can modify them at runtime - and when I say 'modify', I mean things like adding/replacing/removing attributes, including methods and class (which are attributes too...). -- http://mail.python.org/mailman/listinfo/python-list

Have you read the two papers in IBMDeveloperWorks about metaclasses? There is also a third one, about avoiding metaclasses, which is waiting for publication.

Metaclass uses?
Hi, Recently I posted a question about the factory pattern in python. I ve implemented this following one of the ideas posted. After some reading I ve seem a lot of Aspect Oriented Programming mentioned but I m not really sure what it is. Can anyone help me understand how metaclasses can improve the quality of my code and let me do better things. Also is there anymore interesting OO stuff that Python has apart from Java. Many Thanks Nathan -- http://mail.python.org/mailman/listinfo/python-list
