Sehen wir uns nun an, wie Sie damit eine benutzerdefinierte Response zurückgeben können.

Nehmen wir an, Sie möchten eine [XML](https://en.wikipedia.org/wiki/XML)-Response zurückgeben.

Sie könnten Ihren XML-Inhalt als String in eine `Response` einfügen und sie zurückgeben:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

Ahora, veamos cómo podrías usar eso para devolver un response personalizado.

Digamos que quieres devolver un response en [XML](https://en.wikipedia.org/wiki/XML).

Podrías poner tu contenido XML en un string, poner eso en un `Response`, y devolverlo:

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}
