Und es speichert den zurückgegebenen Wert in einem <abbr title="Mechanismus, der bereits berechnete/generierte Werte zwischenspeichert, um sie später wiederzuverwenden, anstatt sie erneut zu berechnen.">„Cache“</abbr> und übergibt diesen gecachten Wert an alle „Dependanten“, die ihn in diesem spezifischen Request benötigen, anstatt die Abhängigkeit mehrmals für denselben Request aufzurufen.

So, with the same Python type declaration, **FastAPI** gives you data validation.

Notice that the error also clearly states exactly the point where the validation didn't pass.

This is incredibly helpful while developing and debugging code that interacts with your API.
