code: def message(self, message_ids):
          
          if isinstance(message_ids, list):
              message_ids = ','.join([int(id) for id in message_ids])

docs: This will return information about the referenced message. If the id
          is given as a comma-delimited list, one record will be returned for
          each id. In this way you can query a set of messages in a single
          request. Note that you can only give up to 25 ids per request--more
          than that will return an error.
