ここでは、 `item_id` は `int` として宣言されています。

/// check | "確認"

これにより、関数内でのエディターサポート (エラーチェックや補完など) が提供されます。

この例を実行し、ブラウザで <a href="http://127.0.0.1:8000/items/3" class="external-link" target="_blank">http://127.0.0.1:8000/items/3</a> を開くと、次のレスポンスが表示されます:

```JSON
{"item_id":3}
```

/// check | "確認"

To do that, we declare a method `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[12] *}

In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance
