You can't use square-brackets notation like that, unless you've written your class specifically to handle it. More likely, what you want is one of: self.name = filename self.dict["name"] = filename Also, the same problem will occur with the UserDict, which tries to update itself rather than its dict. Actually, a simpler solution might be to have UserDict inherit from dict. I'm not sure what you're trying to achieve here; more detail would help. But if UserDict really is a dict, then you can call self.update, and you can use square-brackets item assignment. I've no idea what you'd gain over just using a dict though.
