Question

我有一副纸牌，我伸出援手。令我震惊的是，我想丢掉上述卡并换一手新牌。我该怎么办？

基本上，我似乎无法丢弃元组。我无法deck.remove(hand)，而且似乎找不到其他方法来摆脱它们。有什么建议么？我的代码如下。（我已经看到了做卡的更好方法，但是我对Python的使用程度还不够高，无法使用类。我只是在寻找一种从卡组中删除手中任何元组的方法。）

import random
import itertools

suits = (" of Hearts", " of Spades", " of Clubs", " of Diamonds")
ranks = ("2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace")

deck = tuple("".join(card) for card in itertools.product(ranks, suits))

hand = random.sample(deck, 5)

print(hand)

for card in deck:
    if card in hand:
        # This is what I'm struggling to fill

Answer 1

使用设置操作。简单的解决方法

deck = tuple(set(deck) - set(tuple(hand))) # removes all the tuples from deck which are there in hand

Answer 2

您不能更改卡座，因为它是元组，但是您可以重新创建它并忽略所有内容。这就是我的意思：

import random
import itertools

suits = (" of Hearts", " of Spades", " of Clubs", " of Diamonds")
ranks = ("2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace")

deck = tuple("".join(card) for card in itertools.product(ranks, suits))

hand = random.sample(deck, 5)

# Removed hand from deck.
deck = tuple(card for card in deck if card not in set(hand))

您可以执行类似的操作以向其中添加项目。如果这种情况经常发生，则最好使用可变容器，例如list或dict，该容器允许您修改其内容而无需重新创建整个容器。
