leetcode(4)，Move Zeroes详解（python）

question：

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].

note：

1.不要复制数列，就在原数列上操作

2.尽可能少的操作

代码如下：

def movezeros(num):    count = len(num)    for i in range(count):        if num[i] == 0:            del num[i]            num.append(0)    print num
