Python学习之路_第七周

这次是实操，上LeetCode找一道题来写，要在Topics: Array下，我选择了下面这道题

思路：

1.将原始数组深复制进类中的

self.origin 

（避免干扰）

2.reset时返回原始数组

3.shuffle时先把self.origin深复制给一个临时变量tmp并对其调用random.shuffle(tmp)并返回

代码：

import random
import copy
class Solution:

    def __init__(self, nums):
        """
        :type nums: List[int]
        """
        self.origin = copy.copy(nums)


    def reset(self):
        """
        Resets the array to its original configuration and return it.
        :rtype: List[int]
        """
        return self.origin

    def shuffle(self):
        """
        Returns a random shuffling of the array.
        :rtype: List[int]
        """
        tmp = copy.copy(self.origin)
        random.shuffle(tmp)
        return tmp

# Your Solution object will be instantiated and called as such:
