Porém, ao utilizar o `secrets.compare_digest()`, isso estará seguro contra um tipo de ataque chamado "timing attacks" (ataques de temporização).

### Ataques de Temporização

Mas o que é um "timing attack" (ataque de temporização)?

Vamos imaginar que alguns invasores estão tentando adivinhar o usuário e a senha.

しかし、Pythonには型や「タイプパラメータ」を使ってリストを宣言する方法があります:

### typingの`List`をインポート

まず、Pythonの標準の`typing`モジュールから`List`をインポートします:

{* ../../docs_src/body_nested_models/tutorial002.py hl[1] *}

### タイプパラメータを持つ`List`の宣言

`list`や`dict`、`tuple`のようなタイプパラメータ（内部の型）を持つ型を宣言するには:

* `typing`モジュールからそれらをインストールします。
* 角括弧（`[`と`]`）を使って「タイプパラメータ」として内部の型を渡します:

```Python
from typing import List

my_list: List[str]
```

You can return it directly.

It accepts the following parameters:

* `content` - A `str` or `bytes`.
* `status_code` - An `int` HTTP status code.
* `headers` - A `dict` of strings.
* `media_type` - A `str` giving the media type. E.g. `"text/html"`.

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.
