When i use this script:

import sys, tweepy, webbrowser

Q = sys.argv[1:] 

class CustomStreamListener(tweepy.StreamListener):

    def on_status(self, status):       
        try:
            print "%st%st%st%s" % (status.text, 
                                      status.author.screen_name, 
                                      status.created_at, 
                                      status.source,)
        except Exception, e:
            print >> sys.stderr, 'Encountered Exception:', e
            pass
    def on_error(self, status_code):
        print >> sys.stderr, 'Encountered error with status code:', status_code
        return True # Don't kill the stream
    def on_timeout(self):
        print >> sys.stderr, 'Timeout...'
        return True 
streaming_api = tweepy.streaming.Stream(auth, CustomStreamListener(), timeout=60)

print >> sys.stderr, 'Filtering the public timeline for "%s"' % (' '.join(sys.argv[1:]),)

streaming_api.filter(follow=None, track=Q)

It comes error like this :

Traceback (most recent call last):
  File "C:/Python26/test.py", line 65, in <module>
    streaming_api = tweepy.streaming.Stream(auth, CustomStreamListener(), timeout=60)
TypeError: __init__() takes at least 4 non-keyword arguments (3 given)

What should I do ?
