### Return a Response Directly

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md){.internal-link target=_blank}.

```Python hl_lines="8  10-11"
{!> ../../../docs_src/response_model/tutorial003_02.py!}
```

This simple case is handled automatically by FastAPI because the return type annotation is the class (or a subclass) of `Response`.

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

!!! info "情報"
    `**second_user_data` は以下を意味します：

    `second_user_data`辞書のキーと値を直接、キーと値の引数として渡します。これは、`User(id=4, name="Mary", joined="2018-11-30")`と同等です。

FastAPI 是一个用于构建 API 的现代、快速（高性能）的 web 框架，使用 Python 并基于标准的 Python 类型提示。

关键特性:

* **快速**：可与 **NodeJS** 和 **Go** 并肩的极高性能（归功于 Starlette 和 Pydantic）。[最快的 Python web 框架之一](#_11)。

* **高效编码**：提高功能开发速度约 200％ 至 300％。*
* **更少 bug**：减少约 40％ 的人为（开发者）导致错误。*
* **智能**：极佳的编辑器支持。处处皆可<abbr title="也被称为自动完成、智能感知">自动补全</abbr>，减少调试时间。
* **简单**：设计的易于使用和学习，阅读文档的时间更短。
* **简短**：使代码重复最小化。通过不同的参数声明实现丰富功能。bug 更少。

Вы можете использовать это, чтобы добавить аргумент `example` для каждого поля:

=== "Python 3.10+"

    ```Python hl_lines="2  8-11"
    {!> ../../../docs_src/schema_extra_example/tutorial002_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="4  10-13"
    {!> ../../../docs_src/schema_extra_example/tutorial002.py!}
    ```

## Оголошення атрибутів моделі

Ви можете використовувати `Field` з атрибутами моделі:

=== "Python 3.10+"

    ```Python hl_lines="11-14"
    {!> ../../../docs_src/body_fields/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="11-14"
    {!> ../../../docs_src/body_fields/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="12-15"

매개변수가 없는 "호출 가능"한 것 역시 매개변수가 없는 *경로 작동 함수*와 동일한 방식으로 적용됩니다.

그래서, 우리는 위 예제에서의 `common_paramenters` 의존성을 클래스 `CommonQueryParams`로 바꿀 수 있습니다.

=== "파이썬 3.6 이상"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002.py!}
    ```

    ```Python hl_lines="9-13"
    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

=== "Python 3.10+"

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py310.py!}
    ```

    ```Python hl_lines="11-15"
    {!> ../../../docs_src/dependencies/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="12-16"

    ```Python hl_lines="12"
    {!> ../../../docs_src/security/tutorial001_an_py39.py!}
    ```

    ```Python  hl_lines="11"
    {!> ../../../docs_src/security/tutorial001_an.py!}
    ```

=== "Python 3.8+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="10"

```Python hl_lines="11"
{!../../../docs_src/query_params_str_validations/tutorial004.py!}
