Leetcode 283.移动零 By Python

Posted 2021-01-07 MartinLwx

思路

我们可以用python的list comprehension来取出所以非0的元素，而且这样取出来会保持原有的相对顺序，再统计先后变化的长度，补上相应的0即可

代码

class Solution(object):
    def moveZeroes(self, nums):
        """
        :type nums: List[int]
        :rtype: void Do not return anything, modify nums in-place instead.
        """
        a = [i for i in nums if i!=0]
        delta = len(nums)-len(a)
        zero = [0 for i in range(delta)]
        nums[:] = a[:] + zero[:]

ps.这才是pythonic的代码啊哈哈哈哈哈哈哈
