__eq__とインスタンスを比較する理由は何ですか？

Question

私は関数createDeckが機能しない理由を理解できません。

class Card: 
    def __init__(self): 
     self.rank = tk.IntVar() 
     self.rank.set(rm.choice(rank)) 
     self.seed = tk.StringVar() 
     self.seed.set(rm.choice(seeds)) 
     self.point = tk.IntVar() 
     self.point.set(self.calculatePoint()) 
     self.value = tk.StringVar() 
     self.value.set(self.calculateValue()) 
     self.name = tk.StringVar() 
     self.name.set(self.calculateName()) 

    def __str__(self): 
     return self.name.get() + ' di ' + self.seed.get() 

    def __lt__(self, other): 
     return self.rank.get() < other.rank.get() 

    def __eq__(self, other): 
     return self.__dict__ == other.__dict__ 

    def __ne__(self, other): 
     return self.rank.get() != other.rank.get() and self.seed.get() != other.seed.get() 

    def __gt__(self, other): 
     return self.rank.get() > other.rank.get() 

class Deck: 
    def __init__(self): 
     self.deck= [] 
     self.name = tk.Label(table, text='Deck', bd=3, relief='flat') 
     self.name.grid(column=0, row=0) 

    def createDeck(self): 
     while len(self.deck) < 40: 
      x = Card() 
      if x not in self.deck: 
       deck.append(x) 
     table.create_text(500,200, text='deck is compose by %d cards' % (len(self.deck))) 

Answer 1

あなたの方法：

def createDeck(self): 
    while len(self.deck) < 40: 
     x = Card() 
     if x not in self.deck: 
      deck.append(x) 

は、未定義の変数deckを持っています。

self.deckにそれを変更する：

def createDeck(self): 
    while len(self.deck) < 40: 
     x = Card() 
     if x not in self.deck: 
      self.deck.append(x)
