TypeError: module.__init__() takes at most 2 arguments (3 given)
提问by lobjc
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:
我在一个名为Object.py. 当我尝试从另一个文件中的此类继承时，调用构造函数会引发异常：
TypeError: module.__init__() takes at most 2 arguments (3 given)
This is my code:
这是我的代码：
import Object
class Visitor(Object):
pass
instance = Visitor() # this line throws the exception
What am I doing wrong?
我究竟做错了什么？
回答by Sheena
Your error is happening because Objectis a module, not a class. So your inheritance is screwy.
你的错误发生是因为Object是一个模块，而不是一个类。所以你的遗产很糟糕。
Change your import statement to:
将您的导入语句更改为：
from Object import ClassName
and your class definition to:
和你的类定义：
class Visitor(ClassName):
or
或者
change your class definition to:
将您的类定义更改为：
class Visitor(Object.ClassName):
etc
回答by Anthony Rutledge
You may also do the following in Python 3.6.1
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:
和你的类定义：
class Visitor(Parent):

Even after @Mickey Perlstein's answer and his 3 hours of detective work, it still took me a few more minutes to apply this to my own mess. In case anyone else is like me and needs a little more help, here's what was going on in my situation.
即使在@Mickey Perlstein 的回答和他 3 小时的侦探工作之后，我仍然花了几分钟时间将其应用到我自己的烂摊子上。如果其他人像我一样需要更多帮助，这就是我的情况。
- responses is a module
- Response is a base class within the responses module
- GeoJsonResponse is a new class derived from Response
- 响应是一个模块
- 响应是响应模块中的基类
- GeoJsonResponse 是从 Response 派生的新类
Initial GeoJsonResponse class:
初始 GeoJsonResponse 类：
from pyexample.responses import Response
class GeoJsonResponse(Response):
def __init__(self, geo_json_data):
Looks fine. No problems until you try to debug the thing, which is when you get a bunch of seemingly vague error messages like this:
看起来不错。没有问题，直到您尝试调试该事物，即当您收到一堆看似模糊的错误消息时，如下所示：
from pyexample.responses import GeoJsonResponse ..\pyexample\responses\GeoJsonResponse.py:12: in (module) class GeoJsonResponse(Response):
E TypeError: module() takes at most 2 arguments (3 given)

The errors were doing their best to point me in the right direction, and @Mickey Perlstein's answer was dead on, it just took me a minute to put it all together in my own context:
错误正在尽最大努力为我指明正确的方向，@Mickey Perlstein 的回答已经死了，我只花了一分钟时间将它们放在我自己的上下文中：
I was importing the module:
我正在导入模块：
from pyexample.responses import Response
when I should have been importing the class:
当我应该导入课程时：
from pyexample.responses.Response import Response
Hope this helps someone. (In my defense, it's still pretty early.)
希望这可以帮助某人。（在我看来，现在还为时过早。）

from Object import Object
or
或者
From Class_Name import Class_name
If Object is a .pyfile.
如果 Object 是一个.py文件。

In my case where I had the problem I was referring to a module when I tried extending the class.
在我遇到问题的情况下，当我尝试扩展类时，我指的是一个模块。
import logging
class UserdefinedLogging(logging):
If you look at the Documentation Info, you'll see "logging" displayed as module.
如果您查看文档信息，您会看到“日志记录”显示为模块。
In this specific case I had to simply inherit the logging module to create an extra class for the logging.
在这种特定情况下，我必须简单地继承日志记录模块来为日志记录创建一个额外的类。
