### Vorzüge von `Annotated` { #advantages-of-annotated }

**Es wird empfohlen, `Annotated` zu verwenden**, anstelle des Defaultwertes in Funktionsparametern, es ist aus mehreren Gründen **besser**. 🤓

Der **Default**wert des **Funktionsparameters** ist der **tatsächliche Default**wert, das ist in der Regel intuitiver mit Python. 😌
