如何从python中的字典中获取随机值 [英] How to get a random value from dictionary in python

问题描述

如何从dict中获得随机对?我正在制作一款游戏，您需要猜测一个国家的首都，并且需要随机出现的问题.

How can I get a random pair from a dict? I'm making a game where you need to guess a capital of a country and I need questions to appear randomly.

dict看起来像{'VENEZUELA':'CARACAS'}

我该怎么做?

推荐答案

一种方法(在Python 2. *中)是:

One way (in Python 2.*) would be:

import random
d = {'VENEZUELA':'CARACAS', 'CANADA':'OTTAWA'}
random.choice(list(d.keys()))

编辑:该问题在原始帖子发布后的几年内已更改，现在要求配对，而不是单个项目.现在最后一行应该是:

EDIT: The question was changed a couple years after the original post, and now asks for a pair, rather than a single item. The final line should now be:

country, capital = random.choice(list(d.items()))
