code: def get(self, name):

          # When using the `schema.validate` decorator asynchronously,
          #   we can return the output desired by raising
          #   `tornado.gen.Return(value)` which returns a
          #   Future that the decorator will yield.
          # In Python 3.3, using `raise Return(value)` is no longer
          #   necessary and can be replaced with simply `return value`.
          #   For details, see:
          # http://www.tornadoweb.org/en/branch3.2/gen.html#tornado.gen.Return
  
          # return res  # Python 3.3
          raise gen.Return(res)
