TypeError: modu .__init__()最多接受2个参数(3个给定参数)

I have defined a class in a file named Object.py. When I try to inherit from this class in another file, calling the constructor throws an exception:

我在名为Object.py的文件中定义了一个类。当我试图在另一个文件中继承这个类时，调用构造函数会抛出一个异常:

This is my code:

这是我的代码:

import Object

class Visitor(Object):
    pass

What am I doing wrong?

我做错了什么?

from Object import ClassName

你的类定义是:

class Visitor(ClassName):

or

或

change your class definition to:

将类定义更改为:

class Visitor(Object.ClassName):
   etc

您还可以在Python 3.6.1中执行以下操作

from Object import Object as Parent

and your class definition to:

你的类定义是:

class Visitor(Parent):
