I use this regularly. Think of the "class attribute" as providing a default for a potential "instance attribute" of the same name. In Python, almost everything from a class can be overridden by the instance (exceptions: some special methods, descriptors). Thus, one can (almost) view a class as a defaults provider for its instances. Class attributes are just one case. -- https://mail.python.org/mailman/listinfo/python-list
