     def takeCards(self, cards):

       if card.value >21 and card ==11: 
        return 1 
       elif not card.value:

     def __str__(self): 
      if self.__cards: 
       card = "" 
       for i in self.__cards: 
        card += str(i) + "\t"

from Hand import Hand 


class Dealer(): 

    def __init__(self,name): 
     super(Dealer,self).__init__() 
     self.name = name 
     pass 

    def takeCards(self,cards): 
     self.__hand.takeCards(cards) 
     pass 

    def clearHand(self): 
     self.Hand.clear(card) 
     pass 

我正在寫一個關於黑傑克的遊戲，但我有一些bug不能修復... 我有兩個班。當我測試我的代碼時，程序說，Dealer對象沒有屬性'Hand'。在清晰的手上。我不知道如何解決這個問題。

我看到的第一個問題是你通過自己訪問手。沒有在您的Dealer類的哪個位置實例化Hand類。您可以在Dealer類中嘗試以下內容。

class Dealer(object): 

    def __init__(self,name): 
     super(Dealer,self).__init__() 
     self.name = name 
     self.__hand = Hand() # Instance Hand so you can use its contents. 
     pass 

    def takeCards(self,cards): 
     self.__hand.takeCards(cards) 
     pass 

    def clearHand(self): 
     # self.Hand.clear(card) 
     self.__hand.clear(card) # fixed this to point to our instance 
     pass
