Either assign self.comparer = None before pickling, or define a __getstate__() method that returns a dict which doesn't include the comparer. Something like def __getstate__(self): d = self.__dict__.copy() del d[comparer] return d See http://docs.python.org/lib/pickle-inst.html Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
