# Klassen als Abhängigkeiten

Bevor wir tiefer in das **Dependency Injection** System eintauchen, lassen Sie uns das vorherige Beispiel verbessern.

## Ein `dict` aus dem vorherigen Beispiel

Im vorherigen Beispiel haben wir ein `dict` von unserer Abhängigkeit („Dependable“) zurückgegeben:

```Python hl_lines="9"
{!> ../../docs_src/dependencies/tutorial001_an_py310.py!}
