## Motivation

Fangen wir mit einem einfachen Beispiel an:

```Python
{!../../docs_src/python_types/tutorial001.py!}
```

Dieses Programm gibt aus:

```
John Doe
```

Die Funktion macht Folgendes:

* Nimmt einen `first_name` und `last_name`.
* Schreibt den ersten Buchstaben eines jeden Wortes groß, mithilfe von `title()`.
