Solve the following python programming problem given the following code:
def __getattr__(self, name) : 
    'This is where we get the function for the verb that was just
        requested.

        From here we can apply the authentication information we have.
        ' 
    if (name not in self.HTTP_METHODS) : 
        raise AttributeError (('%r is not an HTTP method' % caller)) 
request_func = getattr (requests, name, None) 
    if (request_func is None) : 
        raise AttributeError (('%r could not be found in the backing lib' % name)) 
@ wraps (request_func) 
    def caller(url, jsonify = True, **kwargs) : 
        'Hand off the call to Requests.' 
        headers = kwargs.get ('headers', dict ()) 
        headers ['Accept'] = self.ACCEPT_HEADER 
        headers ['User-Agent'] = self.USER_AGENT 
        if (jsonify and ('data' in kwargs) and isinstance (kwargs ['data'], (dict, list))) : 
            kwargs ['data'] = json.dumps (kwargs ['data']) 
            headers ['Content-Type'] = 'application/json' 
kwargs ['timeout'] = kwargs.get ('timeout', (1, 30)) 
        kwargs ['auth'] = kwargs.get ('auth', self._token) 
        kwargs ['headers'] = headers 
        if (not (url [: 4] == 'http')) : 
            url = (self.API_ROOT + url) 
return request_func (url, ** kwargs) 
return caller
