Question

我是Python OOP的新手，我正在构建一个Blackjack游戏，以提高我对OO Python的理解和实现。

这是我到目前为止为我的Deck和Card课程所写的内容：

import random

class Deck:
    def __init__(self):
        # init variables
        self.cards = []
        self.numCards = 0
        self.populate_cards()

    def deal(self):
        return self.cards.pop(random.randint(0, (self.numCards - 1)))

    def populate_cards(self):
        for suit in range (0, 5):
            for face in range (0, 13):
                card = Card(face, suit)
                self.cards.append(card)
                self.numCards = self.numCards + 1

    def cards_left(self):
        print (self.numCards)
        print (self.cards)

class Card:
    def __init__(self, face = 0, suit = 0):
        self.face = face
        self.suit = suit

    def assign_value_using_face(self):
        pass

当我执行Python提示时，我会在将Cards.py文件导入Python后尝试创建Deck实例。

>>> from Cards import *
>>> deck = Deck()

但是，我一直收到错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Cards.py", line 8, in __init__
    self.populate_cards()
AttributeError: Deck instance has no attribute 'populate_cards'

我浏览了Stackoverflow，发生此错误的所有情况都没有正确使用＆＃34; self。＆＃34;在populate_cards（）前面，或者没有通过＆＃34; self＆＃34; populate_cards的参数，我正在做的两件事。有人可以帮忙吗？提前谢谢！

AttributeError：Y实例没有属性'X'
