以下是Black Jack测试案例中的课程及其关系。

在python IDLE中我导入“BlackJackGame”并将“game”变量绑定到“BlackJackGame()”，因此我初始化了一个黑杰克游戏。

现在如果我想初始化很多Black Jack游戏，我希望“Card”类在每个游戏中都有不同的属性呢？

例如，在一个黑杰克游戏中，卡片将具有经典套装，例如['Diamond', 'Club', 'Heart', 'Spade']，而在其他情况下，它们会制作套装，例如['Test1', 'Test2', 'Test3', 'Test4']。

简而言之，当我将BlackJackGame()绑定到变量时，如何修改“Card”类属性，以便Black Jack的不同游戏有不同类型的卡？

编辑：我编写了一个测试用例，以便在实践中显示此问题

class Card(object):
    def __init__(self, attribute = 'Test 1'):
        self.attribute = attribute

class Player(object):
    def __init__(self):
        self.card = Card()

class Deck(object):
    def __init__(self, card = Card()):
        self.card = card


class MainDeck(object):
    def __init__(self, deck = Deck()):
        self.deck = deck

class BlackJackGame(object):
    def __init__(self, maindeck = MainDeck(), player = Player()):
        self.maindeck = maindeck
        self.player = player

#Initializing first game
game1 = BlackJackGame()

#We access "Card" classes that reside in "Deck" and "Player",
#to test "Card" class's variable.
print(game1.maindeck.deck.card.attribute) #Prints 'Test 1'
print(game1.player.card.attribute)   #Prints 'Test 1'

#Initializing second game, but this time so that "Card" class's
#attribute has a different value, when card is in "Deck"
game2 = BlackJackGame(maindeck = MainDeck(deck = Deck(card = Card(attribute = 'Test 2'))))

#We test if the attribute assignment works correctly
print(game2.maindeck.deck.card.attribute) #Prints 'State 2'

现在你看，在第二个黑杰克游戏中，我希望Card具有与第一个不同的属性值，但是我这样做的方法非常痛苦，而且它只会改变Cards中的Deck，我希望Card在不同的黑杰克游戏中拥有不同类型的属性值。

Answer 1

Card = namedtuple('Card', 'attribute value')

class Deck(object):
    def __init__(suits, basic_card):
        '''Take list of suits'''
        self.cards = [basic_card._replace(suit=suit, value=value)
                      for value in range(1, 14)
                      for suit in suits]

用法：

poker = BlackJackGame(Deck(suits=['Hearts', 'Spades', 'Clubs', 'Diamonds'],
                           basic_card=Card(attribute='Test 1', value=0))

uno = BlackJackGame(Deck(suits=['Red', 'Yellow', 'Green', 'Blue'],
                         basic_card=Card(attribute='Test 2', value=0)))

更改类属性
