### Bước 5: Nội dung trả về

```Python hl_lines="8"

```

Bạn có thể trả về một `dict`, `list`, một trong những giá trị đơn như `str`, `int`,...

Bạn cũng có thể trả về Pydantic model (bạn sẽ thấy nhiều hơn về nó sau).

違いが分からない場合は、[Async: *"急いでいますか？"*](../async.md#_1){.internal-link target=_blank}を確認してください。

`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
{

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### 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. 🪄
