Solve the following python programming problem given the following code:
def authorize(self, http) : 
    "Authorize an httplib2.Http instance with these Credentials

    Args:
       http - An instance of httplib2.Http
           or something that acts like it.

    Returns:
       A modified instance of http that was passed in.

    Example:

      h = httplib2.Http()
      h = credentials.authorize(h)

    You can't create a new OAuth
    subclass of httplib2.Authenication because
    it never gets passed the absolute URI, which is
    needed for signing. So instead we have to overload
    'request' with a closure that adds in the
    Authorization header and then calls the original version
    of 'request()'.
    " 
    request_orig = new_request.request 
    signer = oauth.SignatureMethod_HMAC_SHA1 () 
    def new_request(uri, method = 'GET', body = None, headers = None, redirections = httplib2.DEFAULT_MAX_REDIRECTS, connection_type = None) : 
        'Modify the request headers to add the appropriate
      Authorization header.' 
        response_code = 302 
        http.follow_redirects = False 
        while (response_code in [301, 302]) : 
            if (self._requestor is None) : 
                raise MissingParameter ('Requestor must be set before using TwoLeggedOAuthCredentials') 
parsed = list (urlparse.urlparse (uri)) 
            q = parse_qsl (parsed [4]) 
            q.append (('xoauth_requestor_id', self._requestor)) 
            parsed [4] = urllib.urlencode (q) 
            uri = urlparse.urlunparse (parsed) 
            req = oauth.Request.from_consumer_and_token (self.consumer, None, http_method = method, http_url = uri) 
            req.sign_request (signer, self.consumer, None) 
            if (headers is None) : 
                headers = { 
                    
} 
headers.update (req.to_header ()) 
            if ('user-agent' in headers) : 
                headers ['user-agent'] = ((self.user_agent + ' ') + headers ['user-agent']) 
else : 
                headers ['user-agent'] = self.user_agent 
(resp, content) = request_orig (uri, method, body,...

    
    

    Fix the buggy line: request_orig = new_request.request
assistant
#Here is Python code to fix the buggy line: request_orig = new_request.

request_orig = http.request
