TypeError: module.__init__() takes at most 2 arguments (3 given)

Solution 1:

Your error is happening because Object is a module, not a class. So your inheritance is screwy.

Change your import statement to:

from Object import ClassName

and your class definition to:

class Visitor(ClassName):

or

change your class definition to:

class Visitor(Object.ClassName):
   etc

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.

• responses is a module
• Response is a base class within the responses module
• GeoJsonResponse is a new class derived from Response

Initial GeoJsonResponse class:

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:

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)

(no name 'PyExample\ tests\test_geojson.py::TestGeoJson::test_api_response' in any of [])

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:

I was importing the module:

from pyexample.responses import Response

when I should have been importing the class:

from pyexample.responses.Response import Response

Hope this helps someone. (In my defense, it's still pretty early.)

Solution 3:

from Object import Object

or

From Class_Name import Class_name

If Object is a .py file.
