1. Das ist die Generatorfunktion. Es handelt sich um eine „Generatorfunktion“, da sie `yield`-Anweisungen enthält.
2. Durch die Verwendung eines `with`-Blocks stellen wir sicher, dass das dateiartige Objekt geschlossen wird, nachdem die Generatorfunktion fertig ist. Also, nachdem sie mit dem Senden der Response fertig ist.

## Dependencies with `yield` and `HTTPException` { #dependencies-with-yield-and-httpexception }

You saw that you can use dependencies with `yield` and have `try` blocks that try to execute some code and then run some exit code after `finally`.

You can also use `except` to catch the exception that was raised and do something with it.
