随机列出单词而不重复 [英] Listing words randomly without repeating them

问题描述

我刚刚从《 Python绝对入门入门》一书中学习了如何在python中创建列表，并遇到了一个挑战，要求随机列出单词而不重复它们.我一直在尝试这样做，因为这本书没有给您答案.到目前为止，这是我的代码:

I just finished learning how to do lists in python from the book,Python Programming for the Absolute Beginner, and came across a challenge asking to list out words randomly without repeating them. I have been trying to do it since the book doesn't gives you the answer to it. So far this is my code:

WORDS = ("YOU","ARE","WHO","THINK")
for word in WORDS:
    newword=random.choice(WORDS)
    while newword==word is False:
          newword=random.choice(WORDS)
          word=newword
          print(word)

很明显，由于单词在列表中重复出现，因此代码无法正常工作.

As obvious as it seems, the code didn't work out as the words repeat in lists.

推荐答案

您可以将shuffle用于列表而不是元组.

You could use shuffle with a list instead of a tuple.

import random
lst = ['WHO','YOU','THINK','ARE']
random.shuffle(lst)
for x in lst:
   print x

请参见此Q/A 也在这里. 要将元组转换为列表，请执行以下操作: Q/A

See this Q/A here also. To convert a tuple to list: Q/A

如果坚持使用元组，则为完整代码:

The whole code if you insist on having a tuple:

import random
tuple = ('WHO','YOU','THINK','ARE')
lst = list(tuple)
random.shuffle(lst)
for x in lst:
   print x
