### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

まず、`OAuth2PasswordRequestForm` をインポートし、`/token` の path operation に `Depends` で依存関係として使います:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` は次のフォームボディを宣言するクラス依存関係です:

- `username`
- `password`
- スペース区切りの文字列で構成される、オプションの `scope` フィールド

   * population, this is an estimator of the population standard deviation of the population which
   * is less biased than {@link #populationStandardDeviation()} (the unbiased estimator depends on
   * the distribution). The count must be greater than one.
   *
   * <p>This is not guaranteed to return zero when the dataset consists of the same value multiple

## Annotation de type vs `Depends` { #type-annotation-vs-depends }

Remarquez que nous écrivons `CommonQueryParams` deux fois dans le code ci‑dessus :

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.10+ sans Annotated

/// tip | Astuce

## Аннотация типа и `Depends` { #type-annotation-vs-depends }

Обратите внимание, что в приведенном выше коде мы два раза пишем `CommonQueryParams`:

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.10+ без Annotated

/// tip | Подсказка

## Anotación de tipos vs `Depends` { #type-annotation-vs-depends }

Nota cómo escribimos `CommonQueryParams` dos veces en el código anterior:

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.10+ sin `Annotated`
