通过对象传递同一类的多个实例

Question

class Card:

        exit()

#c=Card(1,'spades')

class Deck:

    self.deck=[Card(i,j) for i in Card.allRanks for j in Card.allSuits]
    #for i in Card.allRanks:
    #    for j in Card.allSuits:
    #        self.deck.append(Card(i,j))

def shuffle(self):

class Dealer(object):

    def __init__(self, deck, cards, num_players):
        self.deck=deck
        self.num_players=num_players
        self.cards=cards

    def deal(self):
        self.deck.shuffle()
        deal_list=[[] for i in range(self.num_players)] #returns a list of lists
        #say you have 4 players you will have [[hand1],[hand2],[hand3],[hand4]] where hand1=[5 cards]
        #now you pass this to the hand variable
        for i in range(self.cards):
            for j in range(self.num_players):

        return deal_list

class Dealer_better(object):

    def __init__(self, deck, cards, *args):
        self.deck=deck
        self.cards=cards

    def deal(self):
        self.deck.shuffle()
        deal_list=[[] for i in range(len(*args))] #returns a list of lists
        #say you have 4 players you will have [[hand1],[hand2],[hand3],[hand4]] where hand1=[5 cards]
        #now you pass this to the hand variable
        for i in range(self.cards):

class Player(object):

    def __init__(self, hand=[]):
        self.hand=hand

您好，我有 Dealer 和 Dealer_better 课程。它接受来自 Deck() 的对象，并且必须向 n 个玩家发牌。

在 Dealer 类中，我将需要发牌的玩家数量作为变量直接传递给，并生成一个列表列表，其中每个玩家的手牌都是一个列表。

我想在 Deal_better 中改进这一点，并在初始化多个 Class Player 实例后将播放器对象直接传递给 Deal_better。有没有办法传递 *player_objects 类似于 *args。

这样我就可以获得以下功能， p1=Player() p2=Player() p3=Player() p4=Player() new_d=Dealer_better(Deck(),p1.hand,p2.hand,p3.hand,p4.hand) new_d.deal() print p1.hand 应该给我玩家的手，或者至少是其中的对象。 如果需要，我可以在播放器中编写一个 add_card 方法以附加到 self.hand。

为了清楚起见，粘贴下面有问题的类。

 class Dealer(object):

    def __init__(self, deck, cards, num_players):
        self.deck=deck
        self.num_players=num_players
        self.cards=cards

    def deal(self):
        self.deck.shuffle()
        deal_list=[[] for i in range(self.num_players)] #returns a list of lists
        #say you have 4 players you will have [[hand1],[hand2],[hand3],[hand4]] where hand1=[5 cards]
        #now you pass this to the hand variable
        for i in range(self.cards):
            for j in range(self.num_players):
               deal_list[j].append(self.deck.topCard())
        return deal_list

对比

class Dealer_better(object):

def __init__(self, deck,cards, *players):
    self.deck=deck
    self.cards=cards
    self.players = players

def deal(self):
    self.deck.shuffle()
    for i in range(self.cards):
        for p in range(len(self.players)):
            self.players[p].addCard(self.deck.topCard())
            print self.players[p].name,len(self.players[p].hand)


class Player(object):

    def __init__(self, name, hand=[]):
        self.hand=hand
        self.name=name

    def addCard(self,card):
        self.hand.append(card)

返回

p1=Player('Bob') p2=Player('Lola') p3=Player('Luigi') p4=Player('Mario') new_d=Dealer_better(Deck(),5,p1,p2,p3,p4) new_d.deal() print len(p1.hand) 返回 20

Answer 1

这样的事情怎么样：

class player(object):
    def __init__(self):
        self.d = []

class dealer(object):
    def __init__(self, *decks): #feel free to add more stuff this is just an example :)
        self.decks = [d for d in decks]

    def deal(self):
        for d in self.decks:
            d.append(1) # just an example
            d.append(2)


p1 = player()
p2 = player()
p3 = player()

d = dealer(p1.d,p2.d,p3.d)
d.deal()
print p1.d # was changed by deal
