    assert response.json() == "1,2"

## 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

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

```Python hl_lines="9"

    ```Python hl_lines="11"
    {!> ../../../docs_src/query_params_str_validations/tutorial008_py310.py!}
    ```

## 📛 🔢

🌈 👈 👆 💚 🔢 `item-query`.

💖:

```

### `Query`のインポート

そのために、まずは`fastapi`から`Query`をインポートします:

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

## デフォルト値として`Query`を使用

パラメータのデフォルト値として使用し、パラメータ`max_length`を50に設定します:

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