在卡列表中选择多个随机项

Question

我想从同一个列表中选择两个单独的随机选项.有没有办法做到这一点,不包括制作单独的名单？

import random


cards = [2,3,4,5,6,7,8,9,10,'King','Queen','Jack']
cards = random.choice(cards)

suits = ['Clubs', 'Hearts', 'Spades', 'Diamonds']
suits = random.choice(suits)

first_card = ("your first card is the {} of {}") .format(cards,suits)
second_card = ("your second card is the {} of {}") .format(cards,suits)

print first_card
print second_card

产量

your first card is the 10 of Spades
your second card is the 10 of Spades

我希望输出相同,但最后一张牌与第一张牌不同; 两张单独的卡片

Answer 1

事先,通过例如列表理解,从数字和套装生成所有卡片.然后random.sample用来挑选两张随机卡片.

import random

figures = [2, 3, 4, 5, 6, 7, 8, 9, 10, 'King', 'Queen', 'Jack']
suits = ['Clubs', 'Hearts', 'Spades', 'Diamonds']

cards = [(figure, suit) for figure in figures for suit in suits]

print(random.sample(cards, 2)) # [(5, 'Hearts'), (7, 'Diamonds')]

虽然,我建议你不要混合整数和字符串来定义你的数字,因为这可能会导致一些混乱.我建议你指定的整数11,12并且13对Jack,Queen并King分别.
