- 然後點擊 "Execute" 按鈕，使用者介面將會向 API 發送請求，並將結果顯示在螢幕上：

### ReDoc API 文件升級

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

<img src="/img/python-types/image02.png">

With that, you can scroll, seeing the options, until you find the one that "rings a bell":

<img src="/img/python-types/image03.png">

## More motivation

Check this function, it already has type hints:

{* ../../docs_src/python_types/tutorial003.py hl[1] *}

///

Das wird:

* Diesen Statuscode mit der Response zurücksenden.
* Ihn als solchen im OpenAPI-Schema dokumentieren (und somit in den Benutzeroberflächen):

<img src="/img/tutorial/response-status-code/image01.png">

/// note | "Hinweis"

Einige Responsecodes (siehe nächster Abschnitt) kennzeichnen, dass die Response keinen Body hat.

Это позволит:

* Возвращать указанный код статуса в ответе.
* Документировать его как код статуса ответа в OpenAPI схеме (а значит, и в пользовательском интерфейсе):

<img src="/img/tutorial/response-status-code/image01.png">

/// note | "Примечание"

Некоторые коды статуса ответа (см. следующий раздел) указывают на то, что ответ не имеет тела.

    page.set_viewport_size({"width": 960, "height": 700})
    # Manually add the screenshot
    page.screenshot(
        path="docs/en/docs/img/tutorial/separate-openapi-schemas/image05.png"
    )

    # ---------------------
    context.close()
    browser.close()


process = subprocess.Popen(
    ["uvicorn", "docs_src.separate_openapi_schemas.tutorial002:app"]
)
try:

    s.parentNode.insertBefore(fess, s);
  })();
</script>
<fess:search></fess:search>
```

An example of Fess Site Search in use is below:

### 그저 현대 파이썬

(Pydantic 덕분에) FastAPI는 표준 **파이썬 3.6 타입** 선언에 기반하고 있습니다. 새로 배울 문법이 없습니다. 그저 표준적인 현대 파이썬입니다.

documentation générée automatiquement et interactive :

<img src="/img/tutorial/path-params/image01.png">

/// info

À nouveau, en utilisant uniquement les déclarations de type Python, **FastAPI** vous fournit automatiquement une documentation interactive (via Swagger UI).

/// tip

You can write Markdown in the `description` field and it will be rendered in the output.

///

With this configuration, the automatic API docs would look like:

<img src="/img/tutorial/metadata/image01.png">

## License identifier

Since OpenAPI 3.1.0 and FastAPI 0.99.0, you can also set the `license_info` with an `identifier` instead of a `url`.

For example:

```Python hl_lines="31"
