# Zusätzliche Datentypen { #extra-data-types }

Bisher haben Sie gängige Datentypen verwendet, wie zum Beispiel:

* `int`
* `float`
* `str`
* `bool`

Sie können aber auch komplexere Datentypen verwenden.

Und Sie haben immer noch dieselbe Funktionalität wie bisher gesehen:

* Großartige Editor-Unterstützung.
* Datenkonvertierung bei eingehenden <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Requests</abbr>.
