Solve the following python programming problem given the following code:
@ _auth_return_future 
def twitter_request(self, path, callback = None, access_token = None, post_args = None, **args) : 
    'Fetches the given API path, e.g., ``statuses/user_timeline/btaylor``

        The path should not include the format or API version number.
        (we automatically use JSON format and API version 1).

        If the request is a POST, ``post_args`` should be provided. Query
        string arguments should be given as keyword arguments.

        All the Twitter methods are documented at http://dev.twitter.com/

        Many methods require an OAuth access token which you can
        obtain through `~OAuthMixin.authorize_redirect` and
        `~OAuthMixin.get_authenticated_user`. The user returned through that
        process includes an \'access_token\' attribute that can be used
        to make authenticated requests via this method. Example
        usage::

            class MainHandler(tornado.web.RequestHandler,
                              tornado.auth.TwitterMixin):
                @tornado.web.authenticated
                @tornado.web.asynchronous
                @tornado.gen.coroutine
                def get(self):
                    new_entry = yield self.twitter_request(
                        "/statuses/update",
                        post_args={"status": "Testing Tornado Web Server"},
                        access_token=self.current_user["access_token"])
                    if not new_entry:
                        # Call failed.
perhaps missing permission?
                        yield self.authorize_redirect()
                        return
                    self.finish("Posted a message!")

        ' 
    if (path.startswith ('http:') or path.startswith ('https:')) : 
        url = path 
else : 
        url = ((self._TWITTER_BASE_URL + path) + '.json') 
if access_token : 
        all_args = { 
            
} 
        all_args.update (args) 
        all_args.update ((all_args or { 
            
})) 
        method = ('POST' if (post_args is not None) else...

    
    

    Fix the buggy line: all_args.update ((all_args or {
assistant
#Here is Python program to fix the buggy line: all_args.
