python - 如何在 while 循环中生成不重复的随机数？ ( python 3)

Question

目前我所拥有的是

import random
def go():
    rounds = 0
    while rounds < 5:
        number = random.randint(1, 5)
        if number == 1:
            print('a')
        elif number == 2:
            print('b')
        elif number == 3:
            print('c')
        elif number == 4:
            print('d')
        elif number == 5:
            print('e')
        rounds = rounds + 1
go()

输出结果类似于

e
e
c
b
e

如何使数字只使用一次并且字母不重复？(例如类似的东西)

a
e
b
c
d

Answer 1

random.sample(population, k)方法返回长度为 k 的指定总体中的唯一值样本。

r = random.sample("abcde", 5)
for element in r:
    print(element)
