Dit betekent:

* De variabele `prices` is een `dict`:

import json
from typing import Any, Dict, Optional

from fastapi.encoders import jsonable_encoder
from starlette.responses import HTMLResponse
from typing_extensions import Annotated, Doc

swagger_ui_default_parameters: Annotated[
    Dict[str, Any],

        """
        Default configurations for Swagger UI.

        You can use it as a template to add any other configurations needed.

* Ontworpen op basis van deze standaarden, na zorgvuldig onderzoek. In plaats van achteraf deze laag er bovenop te bouwen.
* Dit maakt het ook mogelijk om automatisch **clientcode te genereren** in verschillende programmeertalen.

### Automatische documentatie

Interactieve API-documentatie en verkenning van webgebruikersinterfaces. Aangezien dit framework is gebaseerd op OpenAPI, zijn er meerdere documentatie opties mogelijk, waarvan er standaard 2 zijn inbegrepen.

    /** The path of the HTML: /admin/dict/admin_dict.jsp */
    HtmlNext path_AdminDict_AdminDictJsp = new HtmlNext("/admin/dict/admin_dict.jsp");

    /** The path of the HTML: /admin/dict/kuromoji/admin_dict_kuromoji.jsp */
    HtmlNext path_AdminDictKuromoji_AdminDictKuromojiJsp = new HtmlNext("/admin/dict/kuromoji/admin_dict_kuromoji.jsp");

    /** The path of the HTML: /admin/dict/kuromoji/admin_dict_kuromoji_details.jsp */

### Étape 5 : retourner le contenu

```Python hl_lines="8"
{!../../docs_src/first_steps/tutorial001.py!}
```

Vous pouvez retourner un dictionnaire (`dict`), une liste (`list`), des valeurs seules comme des chaines de caractères (`str`) et des entiers (`int`), etc.

Vous pouvez aussi retourner des models **Pydantic** (qui seront détaillés plus tard).
