python - 在 Python 中从字典中获取随机值

Question

我怎样才能从字典中随机得到一对？我正在制作一个 black jack 游戏，因此用户将从

中随机获得一对

deck_of_cards = {'A':11,'2':2,'3':3,'4':4,'5':5,'6':6,'7':7,'8':8,'9':9,'10':10,'J':10,'Q':10,'K':10}

它会被存储在字典

player_deck = {}

我该怎么做？

Answer 1

使用random.choice()

import random
player_deck = {}
deck_of_cards = {'A':11,'2':2,'3':3,'4':4,'5':5,'6':6,'7':7,'8':8,'9':9,'10':10,'J':10,'Q':10,'K':10}

key, value = random.choice(list(deck_of_cards.items()))
player_deck[key] = value

或者如果你想将键和值直接放入字典中，你可以这样做

player_deck = dict([random.choice(list(deck_of_cards.items()))])
