for multi-repo setups.

// An importKey identifies an imported package by import path and source directory
// (directory containing the file containing the import). In practice, the directory
// may always be the same, or may not matter. Given an (import path, directory), an
// importer must always return the same package (but given two different import paths,
// an importer may still return the same package by mapping them to the same package

## 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` :

```Python hl_lines="3"
{!../../../docs_src/query_params_str_validations/tutorial002.py!}
```

## Utiliser `Query` comme valeur par défaut
