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

下面是改写后的代码风格：

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

注意，变量名没有改变，只是对代码进行了一些格式化和注释。
