choice()方法从一个列表，元组或字符串返回一个随机项。
语法

以下是choice()方法的语法：

choice( seq )
Copy after login

注意：此函数是无法直接访问的，所以我们需要导入random模块，然后我们需要使用random对象来调用这个函数。
参数

  • seq -- 这可能是一个列表，元组或字符串...

返回值

该方法返回一个随机项。
例子

下面的例子显示了choice()方法的使用。

#!/usr/bin/python
import random

print "choice([1, 2, 3, 5, 9]) : ", random.choice([1, 2, 3, 5, 9])
print "choice('A String') : ", random.choice('A String')
Copy after login

当我们运行上面的程序，它会产生以下结果：

choice([1, 2, 3, 5, 9]) : 2
choice('A String') : n
Copy after login
