## Validation additionnelle

Nous allons imposer que bien que `q` soit un paramètre optionnel, dès qu'il est fourni, **sa longueur n'excède pas 50 caractères**.

## Importer `Query`

Pour cela, importez d'abord `Query` depuis `fastapi` :

{* ../../docs_src/query_params_str_validations/tutorial002.py hl[3] *}

### Podsumowanie

Podsumowując, musiałeś zadeklarować typy parametrów, treści żądania (body) itp. tylko **raz**, i są one dostępne jako parametry funkcji.

Robisz to tak samo jak ze standardowymi typami w Pythonie.

Nie musisz sie uczyć żadnej nowej składni, metod lub klas ze specyficznych bibliotek itp.
