当卡在Python中是并列的时，程序不能正确循环

Question

我正在创建一个Python应用程序来模拟纸牌游戏战争。在游戏大战中，两个玩家都抽一张牌。获胜者是价值最高的牌。如果抽到的两张牌是平局，玩家必须先抽另一张牌，直到他们抽到不匹配的牌，然后再转入下一回合。在

我写的应用程序应该提示用户，如果他们准备玩一轮。当他们输入“是”时，程序将随机处理两张卡片并打印出赢家。shell中的结果应如下所示：

准备好打一局了吗？是的 玩家甲：4 玩家乙：Q 赢家：玩家B

我几乎把整个程序都写了，但我最纠结的是两张牌打成平手。当两张牌打成平手时，程序应该再抽两张牌，直到两张牌不平手为止。结果如下：

准备好打一局了吗？是的 玩家甲：5 球员乙：5 领带 玩家甲：A 球员乙：3 获胜者：玩家A

目前，当我运行下面的代码时，如果卡牌平局，程序会提示用户再玩一轮。这是不正确的，因为当牌打成平手时，在同一轮中应该再发两张牌。基本上，我认为我需要的是函数war中的while循环，但是我不知道如何设置循环。我目前设置的while循环只是默认回到主功能，然后再画另一张卡。谁能给我提个建议吗？非常感谢大家的帮助。在

我找到了一个有效的while循环。我不确定这是否是编写它的最简洁的方式，但是函数war中的while循环现在可以正常工作了。在

import random
def shuffleDeck():
    suits = {'\u2660','\u2661','\u2662','\u2663'}
    ranks = {'2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'}

    deck = []

    for suit in suits:
        for rank in ranks:
            deck.append(rank + ' ' + suit)

    random.shuffle(deck)
    return deck

def total(hand):
    values = {'2':2, '3':3, '4':4, '5':5, '6':6, '7':7, '8':8, '9':9, '1':10, 'A':14, 'K':13, 'Q':12, 'J':11}
    result = values[hand[0]]
    return result

def dealCard(deck):
    card = deck.pop(0)
    return card

def compareHands(playerOne, playerTwo):
    playerOneTotal, playerTwoTotal = total(playerOne), total(playerTwo)
    if playerOneTotal > playerTwoTotal:
        result = 1
    elif playerOneTotal < playerTwoTotal:
        result = -1
    else:
        result = 0
    return result

def war(playerOneDeck, playerTwoDeck):
    playerOneWins = 0
    playerTwoWins = 0
    ties = 0
    if len(playerOneDeck) > 0:
        playGame = input('Ready to play a round? ')
        if playGame == 'y':
            playerOneCard = dealCard(playerOneDeck)
            playerTwoCard = dealCard(playerTwoDeck)
            print('Player A: ', playerOneCard[0], '\nPlayer B: ', playerTwoCard[0])
            if compareHands(playerOneCard, playerTwoCard) == 1:
                playerOneWins += 1
                print('Winner: Player A')
            elif compareHands(playerOneCard, playerTwoCard) == -1:
                playerTwoWins += 1
                print('Winner: Player B')

            while compareHands(playerOneCard, playerTwoCard) == 0:
                ties += 1
                print('Tie')
                playerOneCard = dealCard(playerOneDeck)
                playerTwoCard = dealCard(playerTwoDeck)
                print('Player A: ', playerOneCard[0], '\nPlayer B: ', playerTwoCard[0])
                if compareHands(playerOneCard, playerTwoCard) == 1:
                    playerOneWins += 1
                    print('Winner: Player A')
                elif compareHands(playerOneCard, playerTwoCard) == -1:

            war(playerOneDeck, playerTwoDeck)

    else:
        print('End of game.  Player A won {} rounds and Player B won {} rounds.'.format(playerOneWins, playerTwoWins))

deck = shuffleDeck()
playerOneDeck = deck[26:]
playerTwoDeck = deck[:26]
war(playerOneDeck, playerTwoDeck)
