如何让卡片在python中工作

Question

这是我到目前为止的代码：

import sys
import os
import random
Question():
    os.system('cls')
    SQ=input('Do you want to play blackjack y/n')
    if(SQ == y or SQ == Y):
        StartGame()
    if(SQ == n or SQ == N):
        sys.exit()
    if(SQ != n and SQ != N and SQ != y and SQ != Y):
        print('You did answer the question with a y or a n which correspond to yes and no accordingly')
        Question()
Question()
StartGame():
    slot1=False
    slot2=False
    slot3=False
    slot4=False
    slot5=False
    slot6=False
    slot7=False
    slot8=False
    slot9=False
    slot10=False
    slot11=False
    slot12=False
    slot13=False
    slot14=False
    slot15=False
    slot16=False
    slot17=False
    slot18=False
    slot19=False

    slot51=False
    slot52=False
    aceHEART = randrange(1, 52)
    aceHEART

我不明白将插槽和随机数生成器放在一起进行随机洗牌的正确方法。 我怎样才能做到它不会尝试在一个插槽中放置多张卡。 我也不知道如何以更有效的方式管理这些卡。 我正在用python制作一个二十一点游戏，我不知道解决这个问题的正确方法。 请尽你所能帮助我。

Answer 1

不确定你想做什么，但这里有一种方法可以生成一副洗牌：

ranks = ['2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A']
suite = ['clubs', 'hearts', 'spades', 'diamonds']
deck = [r + ' ' + s for r in ranks for s in suite]
random.shuffle(deck)

或与对象：

class Card(object):
    def __init__(self, rank, suite):
        self.rank = rank
        self.suite = suite
deck = [Card(r,s) for r in ranks for s in suite]
random.shuffle(deck)

Answer 2

学会爱列表，用数字来表示卡片，而不是字符串。下面是一个简单的卡片类，应该可以很好地工作：

class Card(object):
    def __init__(self, rank, suit):
        self.rank = rank
        self.suit = suit
    def __str__(self):
        return "23456789TJQKA"[self.rank] + "cdhs"[self.suit]

然后创建只是牌列表的套牌和手牌：

deck = [ Card[r,s] for r in range(13) for s in range(4) ]
random.shuffle(deck)

例如，为什么要使用手牌和牌组列表，因为发牌很简单：

hand.append(deck.pop())

为什么要使用数字而不是字符串来表示卡片等级，以便可以添加和比较它们。您可以在上面的 Mihai 代码中添加一个"值"成员，这会有所帮助。在我的身上，你只需要稍微调整一下数字：

def bjTotal(hand):
    total = 0
    hasAce, isSoft = False, False
    for card in hand:
        if card.rank == 12:
            hasAce = True
            total += 1
        elif card.rank > 7:
            total + 10
        else:
            total += card.rank + 2
    if hasAce and total < 12:
        isSoft = True
        total += 10
    return total, isSoft

Answer 3

类在表示纸牌和游戏方面做得很好

import random
class Card:
     def __init__(self,rank,suit):
        self.rank = rank
        self.suit = suit
     def rankName(self):
        return "A23456789TJQK"[self.rank]
     def suitName(self):
        return "HCDS"[self.suit]
     def __int__(self):
        if self.rank > 8: return 10
        if self.rank == 0:return 11
        return self.rank + 1
     def __eq__(self,other):
        try:
            return self.rank == other.rank
        except:
            return self.rank == other
     def __str__(self):
        return self.rankName() +self.suitName()
     def __repr__(self):
        return "<Card: %s>"%self
class Deck:
    def __init__(self,cards=None):
        if cards is None:
           cards = [Card(rank,suit) for rank in range(13) for suit in range(4)]
        self.cards = cards
        random.shuffle(self.cards)
    def draw(self):
        return self.cards.pop(0)
    def __add__(self,other):
        return Deck(self.cards+other.cards)

class Hand:
    def __init__(self):
        self.cards = []
    def __int__(self):
        total = sum(map(int,self.cards))
        aces = self.cards.count(0)
        while aces > 0 and total > 21:
            aces -= 1
            total -= 10
        return total
    def put(self,card):
        self.cards.append(card)
    def __str__(self):
        return ", ".join(map(str,self.cards))
    def __repr__(self):
        return "<Hand %s>"%self.cards

有了课程后，您现在可以开始构建游戏了

class Game:
      def __init__(self,n_players=1,use_dealer=True):
         self.main_deck = Deck()+Deck() # 2 deck shoe
         self.n_players = n_players
         self.dealer = use_dealer
      def play_hand(self,hand):
         while int(hand) <= 21 and raw_input("%rnHit?"%hand)[0].lower() == "y" :
              hand.put(self.main_deck.draw())
         if int(hand) > 21:
              print "BUST!!!"
      def play_game(self):
         current_player = 0
         hands = [Hand() for _ in range(self.n_players+self.dealer)]
         for i in range(2):
             for hand in hands:
                 hand.put(self.main_deck.draw())
         while current_player < len(hands) - self.dealer:
               self.play_hand(hands[current_player])
               current_player += 1
         if self.dealer:
            while int(hands[-1]) < 17:
                hands[-1].put(self.main_deck.draw())
                print "DEALER HITS:",hands[-1]
         print "FINAL SCORES:"
         print "n".join("%s. %r %d"%(i,h,h) for i,h in enumerate(hands))

game = Game()
game.play_game()

（反正类似的东西）
