在系列中选择一个随机数(python) [英] Selecting a random number within a series(python)

问题描述

我正在尝试创建一个程序，从一系列 2 个数字中选择一个随机数，有谁知道这是如何完成的?我查了一下，说要使用选择函数，但是出现了一个错误，说当代码只需要 2 个参数时，我给出了 3 个参数.

I'm trying to create a program that picks a random number out of a series of 2 numbers, does anyone know how this is done? I looked it up and said to use the choice function, however an error came up saying I had given 3 arguments when the code needed only 2.

我该怎么做才能让它在一个系列中选择一个随机数?

What do I have to do to make it pick a random number in a series?

variable = [choice(a,b),choice(a,b)]
variable = choice(1,5,9,27) #  variable should now = 1, 5, 9 or 27.

推荐答案

As 文档说明，只需写choice((1, 5, 9, 27)).

如果你写choice(1, 5, 9, 27)，那就是向函数传递四个参数.

If you write choice(1, 5, 9, 27), that is passing four arguments to the function.

如果你写choice((1, 5, 9, 27))，那就是传递一个参数，一个由四个元素组成的元组，(1, 5, 9, 27), 到函数.

If you write choice((1, 5, 9, 27)), that is passing a single argument, a tuple of four elements, (1, 5, 9, 27), to the function.
