似乎无法从列表中获取对象

Question

所以我目前的二十一点项目有问题。我目前正在尝试创建一个班级甲板（下面的代码）

import random

class Cards:
    def __init__(self, suit, number):
        self.suit = suit
        self.number = number
    def display_card(self):
        print("{} of {}".format(self.number,self.suit))
    def card_syntax(self):
        if self.number == 1:
            self.number = "Ace"
        if self.number == 11:
            self.number = "Jack"
        if self.number == 12:
            self.number = "Queen"
        if self.number == 13:
            self.number = "King"

        print("{} of {}".format(self.number, self.suit))

class Deck:
    def __init__(self):
        self.cards = []
        self.card_characterists()

    def card_characterists(self):
        for suit in ["Hearts", "Spades", "Clubs", "Diamonds"]:
            for number in range(1,14):
                self.cards.append(Cards(suit,number))

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

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

    def show(self):
        for c in self.cards:
            print(c)

我遇到的问题与 Deck 类中的 show() 方法有关。我尝试使用 FOR 循环来获取对象。

def show(self):
    for c in self.cards:
        print(c)

我似乎得到了以下结果：

有没有办法从 self.cards() 中获得可读的结果。这是我的第一篇文章，所以我希望您不要介意这句话的措辞不当。

Answer 1

将__str__ 添加到Cards。

阅读more。

见下文

class Cards:
    def __init__(self, suit, number):
        self.suit = suit
        self.number = number
    def __str__(self):
        return f'suit: {self.suit}, number: {self.number}'
