2's final output is the same, because both the Disk Memory object or objects, their attributes self.responseresults point is response to this object, so the final value is assigned by the last time

TypeError: Object of type 'Response' is not JSON serializable

The reason: The returned object can not be instantiated (json.dumps (ret)), and finally the return of objects rather than use json dictionary
