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!}
```

デフォルト値`None`を`Query(default=None)`に置き換える必要があるので、`Query`の最初の引数はデフォルト値を定義するのと同じです。

なので:

```Python
q: Optional[str] = Query(default=None)
```

...を以下と同じようにパラメータをオプションにします:

```Python
q: Optional[str] = None
```

しかし、これはクエリパラメータとして明示的に宣言しています。
