在Python中随机化字符串列表的最佳方法 [英] Best way to randomize a list of strings in Python

问题描述

我收到一个字符串列表作为输入，并且需要返回具有这些相同字符串但以随机顺序排列的列表.我必须允许重复-同一字符串在输入中可能出现一次或多次，并且在输出中必须出现相同的次数.

I receive as input a list of strings and need to return a list with these same strings but in randomized order. I must allow for duplicates - same string may appear once or more in the input and must appear the same number of times in the output.

我看到了几种强力"方式(使用循环，禁止使用)，我目前正在使用其中一种方式.但是，知道Python可能会完成一项工作，对吧?

I see several "brute force" ways of doing that (using loops, god forbid), one of which I'm currently using. However, knowing Python there's probably a cool one-liner do get the job done, right?

推荐答案

>>> import random
>>> x = [1, 2, 3, 4, 3, 4]
>>> random.shuffle(x)
>>> x
[4, 4, 3, 1, 2, 3]
>>> random.shuffle(x)
>>> x
[3, 4, 2, 1, 3, 4]
