python - 序列中的随机字符串

Question

有没有办法像整数一样随机化一组字符串？

我举个例子：

import random
random.randint(1, 30) #will produce random number between 1 and 30

对于一个字符串，我想从一组变量中随机化单词：

a="off","it","on","not"
random.randstr(a) #I understand that this isnt a real code and will produce and error

有没有一种简单的方法可以使这成为可能？

Answer 1

试试这个，这是惯用的解决方案：

import random
a = ['off', 'it', 'on', 'not']
random.choice(a)
=> 'on' # just an example, it's a random output

上面的代码使用了该choice()函数，请查看文档以获取更多详细信息。

Answer 2

像这样：

a = ["off","it","on","not"]
a[random.randint(0, len(a))]
