#### Using `Union` or `Optional` { #using-union-or-optional }

If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

* `$`: danach endet, keine weiteren Zeichen hat als `fixedquery`.

Wenn Sie sich verloren fühlen bei all diesen **„Regulärer Ausdruck“**-Konzepten, keine Sorge. Reguläre Ausdrücke sind für viele Menschen ein schwieriges Thema. Sie können auch ohne reguläre Ausdrücke eine ganze Menge machen.

Aber wenn Sie sie brauchen und sie lernen, wissen Sie, dass Sie sie bereits direkt in **FastAPI** verwenden können.

* If the PR can be simplified in a way, you can ask for that, but there's no need to be too picky, there might be a lot of subjective points of view (and I will have my own as well 🙈), so it's better if you can focus on the fundamental things.

### Tests { #tests }

* Help me check that the PR has **tests**.

* Check that the tests **fail** before the PR. 🚨
