HTTP Error 401: Authorization Required in Python



Hi! Iam confused. For the last two weeks i have been trying to connect my appi via Python, typing and typing my Consumer Num, Consumer Secret, Access Token and Access Token Secret but the message is the same again.
auth = twitter.oauth.OAuth(OAUTH_TOKEN, OAUTH_TOKEN_SECRET,
twitter_stream = twitter.TwitterStream(auth=auth)
stream = twitter_stream.statuses.filter(track=word)
If someone can help me i will be so grateful.
