That's because, while you can *think of* Python name bindings as being like dict key/value pairs, they aren't always that. Function locals, class locals, and other such namespaces aren't necessarily implemented with dicts. They're conceptually still a "dictionary" of sorts, but you can't actually pass anyone a dict and key and expect it to work. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
