如何从实例列表中获取类实例对象

奥斯卡·萨拉斯

我有这个代码来生成一个包含一副 Cards 对象实例的列表：

import random
class Cards:

    def __init__(self, Value = random.choice([1,2,3,4,5,6,7,8,9,10,11,12,13]), Group = random.choice(["Diamonds", "Hearts", "Clubs", "Spades"])):
        self.Value = Value
        self.Group = Group

    def printCards(self):
        if self.Value == 11:
            print("J de " + self.Group)
        elif self.Value == 12:
            print("Queen de " + self.Group)
        elif self.Value == 13:
            print("King de " + self.Group)
        else:
            print(str(self.Value) + " de " + self.Group)

def creat_deck():
    list_numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
    list_groups = ["Diamonds", "Hearts", "Clubs", "Spades"]
    list_deck = []
    for number in list_numbers:
        for group in list_groups:
            list_deck.append(Cards(number, group))
    return list_deck

当我打印时，我得到了这个：

print(creat_deck())

    [<__main__.Cards object at 0x02D3D100>, <__main__.Cards object at 0x02D3D070>, <__main__.Cards object at 0x02D3DC70>, ...and so on until the Card object 52]

我该怎么做才能获得实际的卡片，例如：

 [Queen of Diamonds, 7 of Clubs, , ...and so on]

你将要实现__repr__和__str__上Cards：

def __str__(self):
    return f"{self.Value} of {self.Group}"

def __repr__(self):
    return f'{type(self).__name__}({self.Value!r}, {self.Group!r})'
