Wenn Sie wie oben einen Kontextmanager oder einen asynchronen Kontextmanager erstellen, führt dieser vor dem Betreten des `with`-Blocks den Code vor dem `yield` aus, und nach dem Verlassen des `with`-Blocks wird er den Code nach dem `yield` ausführen.

In unserem obigen Codebeispiel verwenden wir ihn nicht direkt, sondern übergeben ihn an FastAPI, damit es ihn verwenden kann.
