拖着一个字

Question

如何在python中随机随机播放单词的字母？

例如,单词"cat"可能会更改为"act","tac"或"tca".

我想这样做而不使用内置函数

Answer 1

import random
word = "cat"
shuffled = list(word)
random.shuffle(shuffled)
shuffled = ''.join(shuffled)
print shuffled

......或者以不同的方式完成,灵感来自Dominic的回答 ......

import random
shuffled = ''.join(random.sample(word, len(word)))

Answer 2

看看Fisher-Yates shuffle.它非常节省空间和时间,并且易于实施.
