Sie könnten das auf der obersten Ebene des Moduls/der Datei machen, aber das würde auch bedeuten, dass **das Modell geladen wird**, selbst wenn Sie nur einen einfachen automatisierten Test ausführen, dann wäre dieser Test **langsam**, weil er warten müsste, bis das Modell geladen ist, bevor er einen davon unabhängigen Teil des Codes ausführen könnte.

Das ist nützlich für Vorgänge, die nach einem Request ausgeführt werden müssen, bei denen der Client jedoch nicht unbedingt auf den Abschluss des Vorgangs warten muss, bevor er die Response erhält.

## Design

Then I spent some time designing the developer "API" I wanted to have as a user (as a developer using FastAPI).

I tested several ideas in the most popular Python editors: PyCharm, VS Code, Jedi based editors.

...but continue reading below to see how to overcome that.

## Return Type and Data Filtering

Let's continue from the previous example. We wanted to **annotate the function with one type**, but we wanted to be able to return from the function something that actually includes **more data**.
