Solve the following python programming problem given the following code:
def get_twit(func) : 
    "Performs oauth and provides the twitter object as kwarg 'twit'." 
    @ wraps (func) 
    def _get_twit(* args, **kwargs) : 
        'Instantiates a Twitter object based on streaming or RESTful.' 
        settings = kwargs.get ('settings', { 
            
}) 
        _twit = None 
        def _lookup_uid(twit) : 
            'Updates settings, adding the `uid` key.' 
            uid = twit.users.lookup (screen_name = settings ['user']) [0] ['id'] 
            settings.update ({ 
                'uid' : uid, 
}) 
if ((not ('twit' in kwargs)) or (kwargs ['twit'] is None)) : 
            oauth = get_oauth () 
            if (settings.get ('stream') and (settings.get ('search') or settings.get ('user'))) : 
                if settings.get ('user') : 
                    twit_rest = twitter.Twitter (auth = oauth) 
                    _lookup_uid (twit_rest) 
twit = twitter.TwitterStream (auth = oauth) 
else : 
                twit = twitter.Twitter (auth = oauth) 
                settings ['stream'] = False 
                if settings.get ('user') : 
                    _lookup_uid (twit) 
_twit = twit 
else : 
            _twit = kwargs ['twit'] 
kwargs.update ({ 
            'twit' : _twit, 
            'settings' : settings,

        return func (* args, ** kwargs) 
return func
