Citation please. I'd like to see where that is defined. Even if it is so defined, the definition is wrong. You can define methods on an instance. I showed an example of an instance with its own personal __dir__ method, and showed that dir() ignores it if the instance belongs to a new-style class but uses it if it is an old-style class. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
