### Step 5: コンテンツの返信

```Python hl_lines="8"

```

`dict`、`list`、`str`、`int`などを返すことができます。

Pydanticモデルを返すこともできます（後で詳しく説明します）。

JSONに自動的に変換されるオブジェクトやモデルは他にもたくさんあります（ORMなど）。 お気に入りのものを使ってみてください。すでにサポートされている可能性が高いです。

## まとめ

* `FastAPI`をインポート
* `app`インスタンスを生成

```

`ModelName.lenet.value` でも `"lenet"` 値にアクセスできます。

#### *列挙型メンバ*の返却

*path operation* から*列挙型メンバ*を返すことができます。JSONボディ（`dict` など）でネストすることもできます。

それらはクライアントに返される前に適切な値 (この場合は文字列) に変換されます。

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

クライアントは以下の様なJSONレスポンスを得ます:

```JSON
{

Você pode retorná-la diretamente.

Ela aceita os seguintes parâmetros:

* `content` - Uma sequência de caracteres (`str`) ou `bytes`.
* `status_code` - Um código de status HTTP do tipo `int`.
* `headers` - Um dicionário `dict` de strings.
* `media_type` - Uma `str` informando o media type. E.g. `"text/html"`.

### Update a Hero with `HeroUpdate`

We can **update a hero**. For this we use an HTTP `PATCH` operation.

And in the code, we get a `dict` with all the data sent by the client, **only the data sent by the client**, excluding any values that would be there just for being the default values. To do it we use `exclude_unset=True`. This is the main trick. 🪄
