抱歉,我是python新手,抱歉,如果问题太简单的话。我正在尝试为一款名为pishti或bastra的纸牌游戏编写代码。很快,两个玩家(在我的例子中是一个用户和一台计算机)每个手都有4张牌,中间有一些卡在上面,玩家可以看到(其他人是封闭的)。很快,我就可以用四个卡片对象的列表为用户处理卡片。但是,在用户玩完他/她的一张卡后,我无法从列表中删除该卡,因为找不到该卡。(我尝试使用.remove()和del)但是,我可以使用list[index]访问卡 这是我的代码(简称为与此问题相关的部分):
import random
class Card:
def __init__(self,value,suit):
self.value = value
self.suit = suit
def __repr__(self):
return f"{self.suit} {self.value}"
def execute(self):
return None
class Deck:
def __init__(self):
suits = ["Hearts","Spades","Clubs","Diamonds"]
values = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"]
self.cards = [Card(value,suit) for value in values for suit in suits]
def __repr__(self):
return f"Deck of {self.count()}"
def count(self):
return len(self.cards)
def shuffle(self):
if self.count() < 52:
raise ValueError ("Sorry only complete decks can be shuffled.")
random.shuffle(self.cards)
return self
def _deal(self,num_of_cards_to_be_dealt):
if self.count() == 0:
raise ValueError ("Sorry, all of the cards have been dealt.")
actual = min(self.count(),num_of_cards_to_be_dealt)
dealt_cards = self.cards[-actual:]
self.cards = self.cards[:-actual]
return dealt_cards
def deal_hand(self,hand_size = 4):
return self._deal(hand_size)
deste = Deck()
kar_deste = deste.shuffle()
orta = (kar_deste.deal_hand())
print(f"The card in the middle: {orta[-1]}")
user_score = 0
comp_score = 0
while kar_deste.count() != 0:
computer_hand = kar_deste.deal_hand()
user = kar_deste.deal_hand()
print(f"Your cards: {user}")
while len(user) != 0:
card_suit = input("Choose a suit: ")
card_val = input("Choose a value: ")
print(str(Card(card_val,card_suit)))
user_turn = Card(card_val,card_suit)
card_index = user.index(user_turn)
del user[card_index]
print(user)
当我运行此代码时,我遇到一个值错误(在user.index()行中),表示该卡不在列表中。但是,我可以通过手动使用它的索引来访问它。因此,我不知道为什么这不起作用。你知道这背后的原因吗?提前谢谢
.index
调用对象的__eq__
方法,因此必须在Card
中实现它。否则,将根据对象的内存地址对其进行比较可能的实施:
