return {'status': True, 'messages': []}

Or perhaps better:

return ResultObject(status=True, messages=[])


I don't see anything here that can't be done by returning a dict, a 
namedtuple (possibly with optional fields), or some other object with 
named fields. They can be optional, they can have defaults, and you can 
extend the object by adding new fields without breaking backwards 
compatibility.
