Estos **type hints** son una nueva sintaxis, desde Python 3.6+, que permite declarar el <abbr title="por ejemplo: str, int, float, bool">tipo</abbr> de una variable.

Usando las declaraciones de tipos para tus variables, los editores y otras herramientas pueden proveerte un soporte mejor.

この場合、関数パラメータ `q` はオプショナルとなり、デフォルトでは `None` になります。

/// check | "確認"

パスパラメータ `item_id` はパスパラメータであり、`q` はそれとは違ってクエリパラメータであると判別できるほど**FastAPI** が賢いということにも注意してください。

///

## クエリパラメータの型変換

`bool` 型も宣言できます。これは以下の様に変換されます:

```Python hl_lines="9"
{!../../docs_src/query_params/tutorial003.py!}
```

この場合、以下にアクセスすると:

```
http://127.0.0.1:8000/items/foo?short=1
```

もしくは、

```
