有多个不同的文件,但这些是唯一重要的部分。上面的代码要求输入,然后根据输入调用hero类。这个类是我必须创建的部分。我创建了一个类Rogue,在这里我用特定的参数调用Hero。我得到以下错误:
File "/Users//Documents/CSC148/Assignment 2/hero.py", line 7, in __init__
Hero.__init__(self.name, None)
File "/Users//Documents/CSC148/Assignment 2/hero.py", line 30, in __init__
self.name = name
builtins.AttributeError: 'str' object has no attribute 'name'
我不是在换绳子,我只是在检查它是否在那儿。为什么它告诉我字符串对于简单的“self.name”构造函数没有属性名?
当你这样做的时候
“self”参数不是作为第一个参数隐式传递的。因此在本例中,您实际上传递了一个字符串(self.name)作为第一个参数(而不是self),而没有传递任何字符串来代替“name”参数。如果“红利”不是关键字参数,则此调用将产生
TypeError: __init__() takes exactly 3 arguments (2 given)
所以: self.name代表self 没有代表名字 奖金初始化为默认值(0,0,0)
Hero.__init__
初始化Hero
对象。要构造新的Hero对象,必须调用Hero
。因此,在Rogue.__init__
中是错误的。您要么要创建一个新的英雄对象:
或者让
Rogue
成为Hero
