#### A Random Item { #a-random-item }

With `data.items()` we get an <abbr title="Something we can iterate on with a for loop, like a list, set, etc.">iterable object</abbr> with tuples containing the key and value for each dictionary item.

We convert this iterable object into a proper `list` with `list(data.items())`.

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.

/// tip

Up to here, everything would work as normally.

But then, when you open the integrated docs UI (the frontend), it would expect to get the OpenAPI schema at `/openapi.json`, instead of `/api/v1/openapi.json`.

* **Kein Kopfzerbrechen**:
    * Keine neue Schemadefinition-Mikrosprache zu lernen.
    * Wenn Sie Pythons Typen kennen, wissen Sie, wie man Pydantic verwendet.
* Gutes Zusammenspiel mit Ihrer/Ihrem **<abbr title="Integrated Development Environment – Integrierte Entwicklungsumgebung: Ähnlich einem Code-Editor">IDE</abbr>/<abbr title="Ein Programm, das Fehler im Quellcode sucht">Linter</abbr>/Gehirn**:

    * Farklı bir syntax öğrenmenize gerek kalmaz,
    * Eğer Python typelarını nasıl kullanacağını biliyorsan Pydantic kullanmayı da biliyorsundur.
