    OpenAPI verlangt, dass jede *Pfadoperation* über eine Beschreibung der Response verfügt.

    Daher, wenn Sie keine vergeben, wird **FastAPI** automatisch eine für „Erfolgreiche Response“ erstellen.

## Description from docstring

As descriptions tend to be long and cover multiple lines, you can declare the *path operation* description in the function <abbr title="a multi-line string as the first expression inside a function (not assigned to any variable) used for documentation">docstring</abbr> and **FastAPI** will read it from there.
