在下面的代码中，它首先工作，但是当我想告诉我经销商有什么卡号时，它会返回一些我不理解的加密内容。
[<__main__.Card object at 0x025A4E50>]
如何让它返回相应的卡号？
也有人说我可能需要在比较事物时使用__eq__而不是我现在的方式可以解释原因，以及如何使用__eq__？
下面是我试图开始工作的程序的代码，它是一个二十一点游戏。

打印卡片而不是卡片对象列表，并为卡片提供一个不错的__str__方法，使其显示为人类可读的。而不是
print(self.player.hand)
试试这个：
for card in self.player.hand:
print(card)
并在class Card插入此内容：
def __str__(self):
return '%s%s' % (self.number, self.suit)
关于__eq__的问题：只要使用__eq__()运算符对相等性进行比较，就会调用对象==方法。如果没有这样的方法，如果它们是同一个对象，则两个对象仅相等。所以在你的卡片中你可能想要这样：
def __eq__(self, other):
return self.number == other.number and self.suit == other.suit

在str()对象上使用Card时，它会调用继承的__str__方法，该方法将打印出对象的类名和地址。你称之为加密的是对象的地址。如果要打印出不同的内容，请覆盖班级中的__str__方法。例如：
class Card(object):
def __str__(self):
return "Card " + self.suit + " " + self.number
