説明文は長くて複数行におよぶ傾向があるので、関数<abbr title="ドキュメントに使用される関数内の最初の式（変数に代入されていない）としての複数行の文字列">docstring</abbr>内に*path operation*の説明文を宣言できます。すると、**FastAPI** は説明文を読み込んでくれます。

docstringに<a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a>を記述すれば、正しく解釈されて表示されます。（docstringのインデントを考慮して）

```Python hl_lines="19-27"
{!../../docs_src/path_operation_configuration/tutorial004.py!}
```

これは対話的ドキュメントで使用されます:

    - [SIG Release](#sig-release)
    - [SIG Scheduling](#sig-scheduling-1)
    - [SIG Storage](#sig-storage-1)

Aqui está um exemplo mais completo.

Utilize uma dependência para verificar se o usuário e a senha estão corretos.

Para isso, utilize o módulo padrão do Python <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> para verificar o usuário e senha.

_tf_api_dir = _os.path.dirname(_os.path.dirname(_API_MODULE.__file__))
if not hasattr(_current_module, "__path__"):
  __path__ = [_tf_api_dir]
elif _tf_api_dir not in __path__:
  __path__.append(_tf_api_dir)

# Import compat before trying to import summary from tensorboard, so that

* Das Gleiche gilt für `app/routers/users.py`, es ist ein weiteres Submodul: `app.routers.users`.
