A "heap" has a technical meaning in programming. To describe the internals of a stack as "heap" will be disconcerting and confusing to anyone who knows about stacks and heaps. > def push (self, word): > self.__heap.append (word) > def pop (self): > if len(self.__heap) == 0: > raise InnerInterpreterError, "stack underflow" "InnerInterpreterError" is the most inappropriate exception name I've ever seen. It has nothing to do with the interpreter, it's a stack error. > result = self.__heap[-1] > del self.__heap[-1] That is better written as result = self.__heap.pop(). -- Steven -- http://mail.python.org/mailman/listinfo/python-list
