Python-如何生成具有多个范围的随机整数? [英] Python- How to generate random integers with multiple ranges?

问题描述

在从(a，b)的不同集合生成X数量的随机整数时，我陷入了困惑.例如，我想生成来自(1,5)，(9,15)和(21,27)的5个随机整数.我的代码生成5个随机整数，但仅生成21到27之间的值，而不会生成其他两个整数.理想情况下，我希望看到的像是1,4,13,22,25，而不是21,21,25,24,27.

I've run into confusion in generating X amount of random integers from different sets of (a,b). For example, I would like to generate 5 random integers coming from (1,5), (9,15),and (21,27). My code generates 5 random integers but only between 21 and 27 and not from the other two. Ideally I'd like to see something like 1,4,13,22,25 instead of 21,21,25,24,27.

我的代码:

from random import randint
n = 0
while n < 5:
    n += 1
    for i in (randint(1,5),randint(9,15),randint(21,27)):
        x = i
    print i

推荐答案

不理想

from random import randint, choice

for _ in range(5):
    print(choice([randint(1,5),randint(9,15),randint(21,27)]))

就像Blender所说的-更清晰的版本

As Blender said - clearer version

from random import randint, choice

for _ in range(5):
    r = choice([(1,5),(9,15),(21,27)])
    print(randint(*r))
