# Fortgeschrittene Python-Typen { #advanced-python-types }

Hier sind einige zusätzliche Ideen, die beim Arbeiten mit Python-Typen nützlich sein könnten.

## `Union` oder `Optional` verwenden { #using-union-or-optional }

Wenn Ihr Code aus irgendeinem Grund nicht `|` verwenden kann, z. B. wenn es nicht in einer Typannotation ist, sondern in etwas wie `response_model=`, können Sie anstelle des senkrechten Strichs (`|`) `Union` aus `typing` verwenden.

    * Dans les requêtes et les réponses, géré de la même manière qu'un `float`.
* Vous pouvez consulter tous les types de données Pydantic valides ici : [Types de données Pydantic](https://docs.pydantic.dev/latest/usage/types/types/).

## Exemple { #example }

Voici un exemple de *chemin d'accès* avec des paramètres utilisant certains des types ci-dessus.
