 7 class Solution:
 8     # 返回从尾部到头部的列表值序列，例如[1,2,3]
 9     def printListFromTailToHead(self, listNode):
10         # write code here
11         result = []
12         head = listNode
13         while head is not None:
14             result.append(head.val)
15             head = head.next
16         result.reverse()　　# 反向列表
