从随机生成的列表中选择-python

Question

我试图在Python中创建一个随机列表。每次运行代码时，列表中的随机单词都会按顺序出现。我想做的是：

import random
numSelect = 0
list = ['thing1', 'thing2', 'thing3', 'thing4', 'thing5']
for i in range(random.randint(1, 3)):
    rThing = random.choice(list)
    numSelect = numSelect + 1
    print(numSelect, '-' , rThing)

目标是要求用户从将要显示的列表中选择一些内容。下面是我想要的输出示例：

1 - thing4

2 - thing2

Which one do you choose?: 

(User would type '2')

*output of thing2*

Answer 1

可以使用random.sample从原始列表中获取子集。

然后可以使用enumerate()对它们进行编号，并使用input询问输入。

import random

all_choices = ["thing1", "thing2", "thing3", "thing4", "thing5"]

n_choices = random.randint(1, 3)
subset_choices = random.sample(all_choices, n_choices)


for i, choice in enumerate(subset_choices, 1):
    print(i, "-", choice)

choice_num = 0
while not (1 <= choice_num <= len(subset_choices)):
    choice_num = int(
        input("Choose (%d-%d):" % (1, len(subset_choices)))
    )

choice = subset_choices[choice_num - 1]

print("You chose", choice)
