Question

我正试图使纸牌游戏变得“傻瓜”。但是当我运行programm时，出现了AttributeError：

输入玩家数量：1   玩家：player1包含：

手值：0追溯（最近一次呼叫最近）：文件“ main.py”，   第25行，在       打印（播放器）文件“ C：\ Users \ kozus \ Desktop \ fool \ fool \ Hand.py”，第38行， str       文字+ =“ \ nHand value：” + str（self.getValue（））文件“ C：\ Users \ kozus \ Desktop \ fool \ fool \ Hand.py”，第20行，位于getValue中       结果+ = self.card.cardPoints（self）文件“ C：\ Users \ kozus \ Desktop \ fool \ fool \ Card.py”，第8行，在cardPoints中       如果self.rank在[“ 10”，“ J”，“ Q”，“ K”，“ A”]中：AttributeError：'Hand'对象没有属性'rank'

这是我的代码：随机导入随机播放

class Card(object):
    def __init__(self, rank, suit):
        self.rank = rank
        self.suit = suit

    def getRank(self):
        return self.rank

    def cardPoints(self):
        # Rerturns amount points for some card
        if self.rank in ["10", "J", "Q", "K", "A"]:
            if self.rank == "A":
                # 11 points for ace
                return 11
            else:
                # 10 points for 10, jack, queen или king
                return 10
        else:
            # Amount points for any other card
            return ["6", "7", "8", "9"].index(self.rank) + 6

    def __str__(self):
        return "%s %s" % (self.rank, self.suit)

class Hand(object):
    def __init__(self, name):
        self.name = name
        self.cards = []
        self.card = Card

    def addCard(self, card):
        # Add card in hand
        self.cards.append(card)

    def getValue(self):
        # Amount points in hand
        result = 0
        # Amount aces in hand
        aces = 0

        for card in self.cards:
            result += self.card.cardPoints(self)

            # If ace in hand then we increasing amount of aces in hand
            if card.getRank() == "A":
                aces += 1

        # Count aces like 1 or 11 points
        if result + aces * 10 <= 21:
            result += aces * 10

        return result

    def __str__(self):
        text = "%s's contains:\n" % self.name

        for card in self.cards:
            text += str(card) + " "

        text += "\nHand value: " + str(self.getValue())

        return text

class Deck(object):
    def __init__(self):
        ranks = ["6", "7", "8", "9", "10", "J", "Q", "K", "A"] # Ranks
        suits = ["D", "C", "H", "S"] # Suits
        self.cards = [Card(r, s) for r in ranks for s in suits] # Generating deck, consists of 36 cards
        shuffle(self.cards)

    def dealCard(self):
        # Card handing over function
        self.cards.pop()

amount_players = int(input("Enter amount of players: "))
deck = Deck() # Creating deck

i = 0

# Creating players
players = [Hand("player{0}".format(i + 1)) for i in range(amount_players)]

print("Players: ")

for player in players:
    # Printing players
    print(player)

for player in players:
    while i < 6:
        # Distrbuting 6 card per player
        player.addCard(deck.dealCard())
        i += 1

for player in players:
    print(player)

现在有人解决了吗？

Answer 1

我认为您不需要card中的Hand属性，因此您应该从Hand构造函数中删除初始化。所有卡已存储在cards中。

这将导致此错误：

  File "/tmp/t.py", line 43, in getValue
    result += self.card.cardPoints(self)
AttributeError: 'Hand' object has no attribute 'card'

在这里，问题在于您不使用card循环迭代变量，因为您使用self在对象中查找了该变量。 cardPoints方法也没有任何参数（隐式self参数除外），所以我们也要解决此问题：

        for card in self.cards:
            result += card.cardPoints()

这将使您摆脱最初的错误。

此后，您将必须更改dealCard方法以实际返回从卡组弹出的卡片，因为dealCard方法当前返回None，而没有return声明。

Answer 2

# Change this line:
result += self.card.cardPoints(self)
# to this:
result += card.cardPoints()

您不需要将对象实例（自身）传递给`cardPoints。以及为什么要这样：

self.card = Card

没有必要，您要做的只是使self.card成为类而不是对象。

Python，纸牌游戏，AttributeError
