## Utiliser `Query` comme valeur par défaut

Construisez ensuite la valeur par défaut de votre paramètre avec `Query`, en choisissant 50 comme `max_length` :

```Python hl_lines="9"
{!../../../docs_src/query_params_str_validations/tutorial002.py!}
```

### Manipuler les *énumérations* Python

La valeur du *paramètre de chemin* sera un des "membres" de l'énumération.

#### Comparer les *membres d'énumération*

Vous pouvez comparer ce paramètre avec les membres de votre énumération `ModelName` :

```Python hl_lines="17"
{!../../../docs_src/path_params/tutorial005.py!}
```

#### Récupérer la *valeur de l'énumération*
