How to use the twitterapi.Status function in TwitterAPI

A sequence of twitterapi.Status instances, one for each message
    '''
    if user:
      url = 'http://twitter.com/statuses/friends_timeline/%s.json' % user
    elif not user and not self._username:
      raise TwitterError("User must be specified if API is not authenticated.")
    else:
      url = 'http://twitter.com/statuses/friends_timeline.json'
    parameters = {}
    if since:
      parameters['since'] = since
    if since_id:
      parameters['since_id'] = since_id
    json = self._FetchUrl(url, parameters=parameters)
    data = simplejson.loads(json)
    return [Status.NewFromJsonDict(x) for x in data]

  @staticmethod
  def NewFromJsonDict(data):
    '''Create a new instance based on a JSON dict.

    Args:
      data: A JSON dict, as converted from the JSON in the twitter API
    Returns:
      A twitterapi.Status instance
    '''
    if 'user' in data:
      user = User.NewFromJsonDict(data['user'])
    else:
      user = None
    return Status(created_at=data.get('created_at', None),
                  favorited=data.get('favorited', None),
                  id=data.get('id', None),
                  text=data.get('text', None),
                  user=user)
