问题出在deal函数中。以下是正文，仅供参考：

card = random.choice(list(deck))
cards_in_hand.append(card)
show_list.append(card)
hand_value = deck.get(card) + value
deck.pop(card)
for card in cards_in_hand:
    if hand_value > 21 and "Ace" in card:
        hand_value = hand_value - 10
        cards_in_hand.remove(card)
return card, hand_value

最后一行：return card, hand_value，大概是要返回随机发牌的卡（您刚刚通过random.choice发牌），以及您当前手牌的总价值。但是，标识符card正被重新用于for循环：for card in cards_in_hand。实际上，您从random.choice(list(deck))获得的卡现在已丢失，并已替换为用于迭代cards_in_hand集合的临时卡。当您到达return语句时，card将具有您的cards_in_hand列表中最后一张卡的值。而且，只有当cards_in_hand不是空的时候，这个错误才会发生，因为如果它是空的，循环就永远不会发生

然而，您还忽略了其他一些事情，尽管它们与您描述的问题关系不大。首先，当庄家问我是否需要另一张卡时，没有什么能阻止我抽越来越多的卡，直到deck变为空，此时线…：

card = random.choice(list(deck))

在deal函数中，…将引发IndexError

此外，还有一些常见的初学者错误-以下是一些代码片段：

while ready_payer_one.upper() != "Y" or "N":

if another_card.upper() != hit or stand:

elif another_card.upper() != hit or stand:

这些片段都犯了同样的错误。尽管Python是一种高级语言，Python源代码有时读起来可能像英语句子，但这些布尔表达式的计算方式与您想象的不同。只要"N"或stand是非空字符串，它们将被计算为“truthy”，并且正如您所知，or只需要它的一个操作数为true，整个表达式就为true。换句话说，您将始终输入这些循环/if语句的主体

如果在程序开头添加一行，定义如下数组： used = [False] * 52 # checks whether the card you are picking has been drawn

然后在deal函数中，您可以将card = random.choice(list(deck))更改为

choice = random.randint(0, 51)
while used[choice] is True:
    choice = random.randint(0, 51)
used[choice] = True
card = list(deck)[choice]

这应该是有效的，因为它会检查卡是否已经被抽出，只有在没有抽出的情况下才会放在你的手中
