Python BlackJack游戏-

Question

我想(随机)打印这副牌中的所有卡片。程序运行并打印最多48张卡(每次执行程序时打印不同数量的卡)。我怀疑我的问题出在get_card()函数中。这是我的第一个程序，所以请友好的(=

import random

class Deck(object):

    def __init__(self,deck={},suit=[],suitDict={},cardValue=0,cardKey={}):
        self.deck=deck
        self.suit=suit
        self.suitDict=suitDict
        self.cardValue=cardValue
        self.cardKey=cardKey

    def create_deck(self):

        spades={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        hearts={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        diamonds={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        clubs={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        self.deck={'Spades':spades,'Clubs':clubs,'Hearts':hearts,'Diamonds':diamonds}
        print 'Deck Created'

    def get_card(self):
        while 1:
            #gets random suit
            self.suit=random.sample(self.deck,1)
            self.suitDict=self.deck[self.suit[0]]
            if self.suit[0] in self.deck:
                #get random key[CARD]
                self.cardKey=random.sample(self.suitDict,1)
                if self.cardKey[0] in self.suitDict:
                    #get card value
                    self.cardValue=self.deck[self.suit[0]].pop(self.cardKey[0])
                    break
                else:
                    self.get_card()
            else:
                self.get_card()
    def return_hand(self):
        self.get_card()
        return [self.suit,self.cardKey,self.cardValue]




d=Deck()
d.create_deck()
x = 52

while x!=0:
    print d.return_hand()
    x-=1

Answer 1

这个答案正好解决了你面临的具体问题，那就是不能从你的扑克牌中拿到所有的牌。为了让你的程序正常工作，我只做了最少的改动。你应该试着让设计和代码更整洁。

代码如下：

import random

class Deck(object):

    def __init__(self,deck={},suit=[],suitDict={},cardValue=0,cardKey={}):
        self.deck=deck
        self.suit=suit
        self.suitDict=suitDict
        self.cardValue=cardValue
        self.cardKey=cardKey

    def create_deck(self):

        spades={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        hearts={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        diamonds={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        clubs={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
        self.deck={'Spades':spades,'Clubs':clubs,'Hearts':hearts,'Diamonds':diamonds}
        print 'Deck Created'

    def empty(self):
        return all(len(suit) == 0 for suit in self.deck.values())

    def get_card(self):
        while 1:
            if self.empty():
                break
            #gets random suit
            self.suit=random.sample(self.deck,1)
            self.suitDict=self.deck[self.suit[0]]
            if self.suitDict and self.suit[0] in self.deck:
                #get random key[CARD]
                self.cardKey=random.sample(self.suitDict,1)
                if self.cardKey[0] in self.suitDict:
                    #get card value
                    self.cardValue=self.deck[self.suit[0]].pop(self.cardKey[0])
                    break
                else:
                    self.get_card()
            else:
                self.get_card()

    def return_hand(self):
        self.get_card()
        return [self.suit,self.cardKey,self.cardValue]

d=Deck()
d.create_deck()
x = 52

while x!=0:
    print d.return_hand()
    x-=1

我建议您在这段代码和您的代码之间运行一次比较，看看到底发生了什么变化。

基本上：

• I添加了一个" empty ()“布尔函数，用于检查纸牌中是否没有剩余的纸牌
• 我每次选择一张新纸牌时，都会检查所选的self.suitDict不是空的，然后再尝试从中随机选择一张纸牌。

我想通了，[=

import random

class Deck(object):

def __init__(self,deck={}):
    self.deck=deck

def create_deck(self):

    spades={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
    hearts={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
    diamonds={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
    clubs={'Ace':[1,10,11],2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:10,'Jack':10,'Queen':10,'King':10}
    self.deck{'Spades':spades,'Clubs':clubs,'Hearts':hearts,'Diamonds':diamonds}

def get_card(self):

    while True:
        #picks random suit from deck // picks random key from deck dict.
        #returns card attr. in a tuple
        suit=random.choice(self.deck.keys())
        if len(self.deck[suit]) > 0:
            #picks random card from suit 
            card=random.sample(self.deck[suit],1)
            cardValue=self.deck[suit].pop(card[0])
            return (suit,card,cardValue)
        else:
            #deletes empty suit from deck.      
            del self.deck[suit]

然后这将随机打印出所有的卡片：

deck=Deck()
deck.create_deck()
for i in range(52):
    print i,deck.get_card()
