打印我在键入“是”后使用的卡片，以便再次玩

Question

我想让这场比赛开始时，每一手牌的剩余从上一手牌。相反，它开始于一个完整的，新洗牌甲板。我怎样才能把它修好继续？ 我根据你的建议更新了代码，但是它没有显示我的展示卡，非常感谢

有关完整的解决方案，请参见repl.it：

有很多问题，这里有几个主要的主题：

如果你不得不重复自己的话，那你就错了：

aces = False
#IF TWO ACES
if player.hand[0].pip == "A" and player.hand[1].pip == "A":
    player.hand[0].pipValue = 1

#check for aces
    for i in player.hand:
        if i.pip == "A" and i.value == 11:
            aces = True

#check if an ace was drawn
        for i in player.hand:
            if i.pip == "A" and i.value == 11:
                aces = True

#check for aces
if aces:
    print ('You hold ' + str(player) + 'for a total of ' + str(player.handTotal))
    print ("Over 21. Value of ace changed to 1")
    #chanlge value of ace and hand
    player.handTotal = player.handTotal - 10
    for i in player.hand:
        if i.pip == "A" and i.value == 11:
            i.value = 1
    #check for other standard aces
    aces = False
    for i in player.hand:
        if i.pip == "A" and i.value == 11:
            aces = True

每一个都用了两次。。。我取而代之的是让我的玩家自己决定它的价值：

@property  
def handTotal(self):
  while sum(card.value for card in self.hand) > 21 and \
        any(card.pip == 'Ace' and card.value == 11 for card in self.hand):
    for card in self.hand:
      if card.pip == 'Ace' and card.value == 11:
        card.value = 1
        break
  return sum(card.value for card in self.hand)

每当有人请求handTotal时，@property修饰符就会强制它重新计算。你知道吗

告诉梅因你想继续玩

您需要以某种方式return一个值返回main。因为您已经有了一些全局状态变量，所以我添加了playing = True，然后：

def message():
    global playing
    again = input("Do you want to play again? (Y/N) : ")
    if again.lower() == "n":
        print("\n\n   -Thank you for playing!    \n\n")
        playing = False
    return True # Tells `turn()` the game is over

Answer 2

是的，你可以从上一场比赛结束的地方继续一场比赛。当前的问题是递归调用main。从头开始，洗牌一整副牌，等等

相反，您需要一个如下所示的主程序：

def main():
    cardDeck = Deck()
    print ('Initial Deck: ')
    print(cardDeck)

    cardDeck.shuffle()
    print ('Shuffled Deck: ')
    print(cardDeck)

    keep_playing = True
    while keep_playing:

        player = Player()
        opponent = Player()

        #give each player 2 cards, alternating
        cardDeck.dealOne(player)
        cardDeck.dealOne(opponent)
        cardDeck.dealOne(player)
        cardDeck.dealOne(opponent)

        print ('Deck after giving 2 cards each')
        print (cardDeck)

        #show 1 faceup card for each player
        showHands(player,opponent)

        #start playing
        playerTurn(cardDeck,player, opponent)
        opponentTurn(cardDeck, opponent, player)

        again = raw_input("Do you want to play again? (Y/N) : ")
        keep_playing = again in "Yy"

    # Reach here after dropping out of the while loop
    print "\n\n   -Thank you for playing!    \n\n"

这样就消除了消息函数和对main的递归调用。你知道吗
