Leetcode 283 Move Zeroes python

题目：

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

python中没有自增运算符++．

 class Solution(object):
     def moveZeroes(self, nums):
         index =
         size = len(nums)
         for i in range(size):
             if nums[i] == :
                 continue
             else:
                 nums[index] = nums[i]
                 index +=
         while index < size:
             nums[index] =
             index +=
