You can return *enum members* from your *path operation*, even nested in a JSON body (e.g. a `dict`).

They will be converted to their corresponding values (strings in this case) before returning them to the client:

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

In your client you will get a JSON response like:

```JSON

  "model_name": "alexnet",

        assertEquals(loadedUser, result);
