### Wir machen Fehler

Wir, als Menschen, machen ständig **Fehler**. Software hat fast *immer* **Bugs**, die an verschiedenen Stellen versteckt sind. 🐛

Und wir als Entwickler verbessern den Code ständig, wenn wir diese Bugs finden und neue Funktionen implementieren (und möglicherweise auch neue Bugs hinzufügen 😅).

For now, you just need to know that `Annotated` exists, and that it's standard Python. 😎

Later you will see how **powerful** it can be.

/// tip

The fact that this is **standard Python** means that you will still get the **best possible developer experience** in your editor, with the tools you use to analyze and refactor your code, etc. ✨
