1 class Solution(object):
2     def rotate(self, nums, k):
3         """
4         :type nums: List[int]
5         :type k: int
6         :rtype: None Do not return anything, modify nums in-place instead.
7         """
8         nums[:] = nums[-k%len(nums):] + nums[0:-k%len(nums)]

代码二：

 1 class Solution(object):
 2     def rotate(self, nums, k):
 3         """

 7         """
 8         while k > 0:
 9             nums.insert(0, nums.pop())
10             k -= 1
