Why this python code didn't pass the test?

    class Solution(object):
        def rotate(self, nums, k):
            """
            :type nums: List[int]
            :type k: int
            :rtype: void Do not return anything, modify nums in-place instead.
            """
            m=len(nums)-k
            nums=nums[m:]+nums[:m]
    

    Idea is the join the last half list and front half list together.

    First time I return nums[m:]+nums[:m] , but it's not what the test want. Then I simply change nums, but it didn't pass the test also.
