How to use the pydomo.Transport.HTTPMethod.PATCH function in pydomo

def patch(self, url, body):
        headers = self._headers_send_json()
        return self.request(url, HTTPMethod.PATCH, headers, {},
                            self._obj_to_json(body))

def update(self, stream_id, stream_update):
        return self._update(self._base(stream_id), HTTPMethod.PATCH, requests.codes.ok, stream_update, self.streamDesc)

def _update(self, url, method, success_code, obj_update, obj_desc):
        if method == HTTPMethod.PUT:
            response = self.transport.put(url, obj_update)
        elif method == HTTPMethod.PATCH:
            response = self.transport.patch(url, obj_update)
        if response.status_code == success_code:
            if str(response.text) == '':
                return
            else:

                self.print_json("Updated", obj)
                return obj
        else:
            self.logger.debug("Error updating " + obj_desc + ": "
                              + self.transport.dump_response(response))
            raise Exception("Error updating " + obj_desc + ": "
                            + response.text)
