!!! tip "Consejo"
    También podrías obtener el valor `"lenet"` con `ModelName.lenet.value`.

#### Devuelve *enumeration members*

Puedes devolver *enum members* desde tu *operación de path* inclusive en un body de JSON anidado (por ejemplo, un `dict`).

```Python hl_lines="20"
{!../../../docs_src/path_params/tutorial005.py!}
```

!!! tip "İpucu"
    `"lenet"` değerine `ModelName.lenet.value` tanımı ile de ulaşabilirsiniz.

#### *Enumeration Üyelerini* Döndürelim

JSON gövdesine (örneğin bir `dict`) gömülü olsalar bile *yol operasyonundaki* *enum üyelerini* döndürebilirsiniz.
