GET() takes exactly 2 arguments (4 given)

I have a web.py application with following server code.

import web
import mod1

urls = (
  '/(\w*)/(c|r|u|d)/(.*)', '\\1.\\2',
)

if __name__ == "__main__": 
    app = web.application(urls, globals())
    app.run()

mod1.py contains 

class c:
    def POST(self):
        return "C"

class d:
    def DELETE(self):
        return "d"

class u:
    def POST(self):
        return "u"

class r:
    def GET(self, _id):
        return "v={0}".format(_id)

Now requesting http://.../mod1/r/3 returns GET() takes exactly 2 arguments (4 given).

What is the problem here?

Your URL configuration has 3 parameters ((\w*), (c|r|u|d) and (.*)). Plus the self argument for methods, that makes 4 arguments.

Adjust your GET method to accept all parameters:

def GET(self, param1, operation, id_):

These match each of the regular expression capturing groups; I guessed at the parameter names for each, you can adjust as needed.
