如何从 10 个字符串中随机选择 5 个字符串

Question

I have one list consisting of 10 questions. How do I choose 5 (max) at random and there can be no doubles - in python.

I have tried using:

from random import choice

strings = ['aa','bb','cc','dd','ee']
print(choice(strings))

But have no Idea how to choose 5 and have no doubles.

Answer 1

The method random.choice() draws samples with replacement . What you want is drawing samples without replacment . This is what random.sample() does.

Example with 5 samples drawn:

print(random.sample(strings, 5))

See the documentation .

Answer 2

This should work:

import random
random.sample(strings, 5)
