Dado que, por padrão, valores singulares são interpretados como parâmetros de consulta, você não precisa explicitamente adicionar uma `Query`, você pode somente:

```Python
q: Union[str, None] = None
```

Ou como em Python 3.10 e versões superiores:

```Python
q: str | None = None
```

Por exemplo:

{* ../../docs_src/body_multiple_params/tutorial004_py310.py hl[26] *}

Par défaut, les valeurs [scalaires](https://docs.github.com/fr/graphql/reference/scalars) sont interprétées comme des paramètres query, donc inutile d'ajouter explicitement `Query`. Vous pouvez juste écrire :

```Python
q: Union[str, None] = None
```

Ou bien, en Python 3.10 et supérieur :

```Python
q: str | None = None
```

Par exemple :

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[27] *}
