在 python 中实现一副纸牌。调用 list.pop() 时尝试打印所有卡片时出现问题

Question

class Card:
    def __init__(self, suit, value):
        self.suit = suit
        self.value = value

    def show(self):
#         print(f"{self.value} of {self.suit}")
        return (self.suit, self.value)


class Deck(Card):
    """
    Deck is collection of 52 cards.
    """

    colour = ('Hearts', 'Diamonds', 'Spades', 'Clubs')
    rank = ('Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten', 'Jack', 'Queen', 'King', 'Ace')
    def __init__(self):

        d = []
        for s in Deck.colour:
            for r in Deck.rank:
                c = Card(s,r)
                d.append(c)
        self.pack = d

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


mydeck = Deck()
j =1
for i in mydeck.pack:
    print(j, "\t", mydeck.draw().show(), " count remaining ", len(mydeck.pack))
    j +=1

在尝试打印列表 mydeck.deck 的内容时，它只打印了总值的一半。如果再次运行，它会打印下一半的值。

请帮我看看为什么所有内容都打印不出来？

我是初学者，非常感谢任何反馈。提前致谢。

Answer 1

只是不要在循环内调用 draw() — i 已经遍历了 mydeck.pack 中的每张卡片，因此您可以只调用 i.show()。您可能希望将 i 重命名为 card。

正如 Ed Ward 在评论中指出的，您也肯定不希望 Deck 继承自 Card。

Answer 2

我是这样修复的：

class Card:
    def __init__(self, suit, value):
        self.suit = suit
        self.value = value

    def show(self):
#         print(f"{self.value} of {self.suit}")
        return (self.suit, self.value)


class Deck():
    """
    Deck is collection of 52 cards.
    """

    colour = ('Hearts', 'Diamonds', 'Spades', 'Clubs')
    rank = ('Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten', 'Jack', 'Queen', 'King', 'Ace')
    def __init__(self):
        d = []
        for s in Deck.colour:
            for r in Deck.rank:
                c = Card(s,r)
                d.append(c)
        self.pack = d

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


mydeck = Deck()
j =1
breakpoint()
for i in mydeck.pack:
    print(j, "\t", i.show(), " count remaining ", len(mydeck.pack)-j)
    j +=1

输出

1        ('Hearts', 'Two')  count remaining  51
2        ('Hearts', 'Three')  count remaining  50
3        ('Hearts', 'Four')  count remaining  49
4        ('Hearts', 'Five')  count remaining  48
5        ('Hearts', 'Six')  count remaining  47
6        ('Hearts', 'Seven')  count remaining  46
7        ('Hearts', 'Eight')  count remaining  45
8        ('Hearts', 'Nine')  count remaining  44
9        ('Hearts', 'Ten')  count remaining  43
10       ('Hearts', 'Jack')  count remaining  42
