Python Headache

This is the first time is used python i keep getting the same error message and i have no idea why:

import urllib
import threading
from mechanize import Browser

class ImageGrabber(threading.Thread):

        def __init__(self,url,imgnum,searchterm):

                self.url=url
                self.imgnum=imgnum
                self.searchterm=searchterm
                threading.Thread.__init__(self)

        def run(self):

                urllib.urlretrieve(self.url,'test')

class ImageResults:

        def grabresults(query):

                br=Browser()
                response=br.open('http://images.google.co.uk/images?hl=en&q=%s&btnG=Search'%(self.query))
                print response.read()

i=ImageResults()
i.grabresults('house')

Code (markup):

results it -> TypeError: grabresults() takes exactly 1 argument (2 given)

 

class ImageResults:

        def grabresults([B]self,[/B] query):

                br=Browser()
                response=br.open('http://images.google.co.uk/images?hl=en&q=%s&btnG=Search'%(self.query))
                print response.read()

Code (markup):

In Python, you have to have this self parameter on the first place of every object method (it is equivalent C++ this).
