【问题描述】：

以下python代码是我正在处理的：

import random

ranks = ["Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King", "Ace"]
suits = ["Spades", "Clubs", "Hearts", "Diamonds"]

class Card:
    def __init__(self, rank, suit):
        self.rank = rank
        self.suit = suit
        
    def print(self):
        print(self.rank, "of", self.suit)

class Deck:
    def __init__(self):
        self.cards = []
        
    def build(self):
        for x in ranks:
            for y in suits:
                self.cards.append(Card(x,y))

    def shuffle(self):
        random.shuffle(self.cards)

    def print(self):
        for x in self.cards:
            x.print()

    def draw(self):
        self.cards.pop()
        
y = Deck()
y.build()
y.shuffle()

class Player:
    def __init__(self):
        self.hand = []

    def take(self):
        self.hand.append()
        
    def print(self):
        for x in self.hand:
            x.print()

z = Player()
z.take()
z.print()

对于我的生活，我似乎无法让 z.take() 和 z.print() 工作。我可以让 Class Deck 弹出一张卡片，然后使用 Class 方法显示它，但我似乎无法将卡片放到 Class Player 的手中。我如何将卡附加到职业玩家的手上？如果有人可以帮助我，我将不胜感激。谢谢。

【问题讨论】：

你可能不应该为你的函数命名 print

在 take() 函数中，您没有在手上添加任何内容。

@BrutusForcus 如果它是一个实例方法就没有那么糟糕了，这样它就不能在没有引用实例的情况下被调用

card = y.pop() z.take(card)。但它需要return self.cards.pop() 和def take(self, card): self.hand.append(card)

【参考方案1】：

首先你应该使用return

    def draw(self):
        return self.cards.pop()

接下来你应该在

中使用参数（即card）

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

然后你就可以了

card = y.draw()
z.take(card)

或

z.take(y.draw())

顺便说一句：

您可以使用更好的名称来代替 x、y、z - 使代码更具可读性。

import random

# --- constants ---  # `UPPER_CASE_NAMES`

RANKS = ["Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King", "Ace"]
SUITS = ["Spades", "Clubs", "Hearts", "Diamonds"]

# --- classes ---

class Card:
    def __init__(self, rank, suit):
        self.rank = rank
        self.suit = suit
        
    def print(self):
        print(self.rank, "of", self.suit)

class Deck:
    def __init__(self):
        self.cards = []
        
    def build(self):
        for rank in RANKS:
            for suit in SUITS:
                self.cards.append(Card(rank, suit))

    def shuffle(self):
        random.shuffle(self.cards)

    def print(self):
        for card in self.cards:
            card.print()

    def draw(self):
        return self.cards.pop()

class Player:
    def __init__(self):
        self.hand = []

    def take(self, card):
        self.hand.append(card)
        
    def print(self):
        for card in self.hand:
            card.print()

# --- functions ---

# empty

# --- main ---

deck = Deck()
deck.build()
deck.shuffle()

player1 = Player()
player2 = Player()

for _ in range(5):
    card = deck.draw()
    player1.take(card)

    card = deck.draw()
    player2.take(card)

print('--- player 1 ---')
player1.print()

print('--- player 2 ---')
player2.print()

带有列表和for循环的版本

因为名称（单个）player 和（多个）players 非常相似，有时会在代码中出错，所以我使用前缀all_ 使all_players 和player 更易于识别。

# --- main ---

deck = Deck()
deck.build()
deck.shuffle()

all_players = [Player(), Player(), Player(), Player()]

for player in all_players:
    for _ in range(5):
        card = deck.draw()
        player.take(card)

for number, player in enumerate(all_players, 1):
    print('--- player', number, '---')
    player.print()
