问题描述

比方说，我必须去变量，狗和猫. Dog = 5，cat =3.我如何告诉Python随机选择这些变量之一并将其打印到屏幕上?

Let's say I have to variables, dog and cat. Dog = 5, and cat = 3. How would I tell Python to pick one of these variables by random and print it to the screen?

推荐答案

import random
print random.choice([dog, cat])

就这么简单. choice()获取一个序列并从中返回随机选择.

It's that simple. choice() takes a sequence and returns a random selection from it.
