Question

运行代码时，我收到错误消息： “ AttributeError：类型对象'Player'没有属性'hkslist'”

为什么我不能从班级内调用列表？想法是，该列表应该从列表中选择两个功能之一，然后在被调用时运行该功能。

完整代码：

Answer 1

hkslist是Player类实例的属性，而不是Player类本身的实例。您可以在hkslist（self.hkslist = [hk1, hk2]）的定义中看到这一点，其中hkslist是在self上定义的。如果要访问hkslist，则需要创建Player的实例。例如：

player = Player()
player.hkslist[player.indhks]()
