A callback is normally a callable you pass to some other function with the expectation that it will be invoked in certain circumstances. That's not really the same thing as something someone else calls: any function that's part of a published api is intended to be called by someone else; but that doesn't really make it a callback. -- https://mail.python.org/mailman/listinfo/python-list
