检查代码并修改：class Node: def init(self, data): self.data = data self.prev = None self.next = None Class DoublyLinkedlist: # def init(self) self.head = None def remove(self,item): current = self.head previous = None found = False while not found: if current.getData() == item found = True else: previous = current current = current.getNext() if previous == None: self.head = current.getNext() current.prev = None else: previous.setNext(current.getNext()) current.prev = previous

改写代码风格并保持变量名，代码意思不变 def prepend(self, value): n = LinkedList.Node(value, prior=self.head, next=self.head.next) self.head.next.prior = self.head.next = n self.length += 1 def append(self, value): n = LinkedList.Node(value, prior=self.head.prior, next=self.head) n.prior.next = n.next.prior = n self.length += 1
