python-3.x - Python 3 TypeError：'int' object is not callable，但这里有什么问题？

Question

目前我正在学习 Python 3，我在二十一点纸牌游戏代码中面临以下问题。

输出是 player.points() 函数的结果，我在编写代码之外对其进行了测试，并且它运行良好，所以我不知道错误消息的来源，有什么提示或想法吗？

Answer 1

在你的Player类中，points是一个整数，不能被调用。我看到该方法points已被注释掉。

    for player in blackjack.table:
        player.points()

从这段代码中，您似乎想要调用 method points，但您却试图调用存储在points属性中的整数。

取消注释该方法，并更改方法或属性的名称。
