Hard to tell when you don't give any code. >>> class A(object): ... @property ... def attribute(self): ... raise AttributeError ... def __getattr__(self, name): ... return "nobody expects the spanish inquisition" ... >>> A().attribute 'nobody expects the spanish inquisition' Do you mean something like this? I don't think the __getattr__() call can be avoided here. Peter -- http://mail.python.org/mailman/listinfo/python-list
