Viele der Tutorials enthalten Codeblöcke.

In den meisten Fällen handelt es sich bei diesen Codeblöcken um vollständige Anwendungen, die unverändert ausgeführt werden können.

Tatsächlich sind diese Codeblöcke nicht Teil des Markdowns, sondern Python-Dateien im Verzeichnis `./docs_src/`.

Und diese Python-Dateien werden beim Generieren der Site in die Dokumentation eingefügt.
