Verás qué otras "cosas", además de funciones, pueden usarse como dependencias en el próximo capítulo.

///

Cada vez que llega un nuevo request, **FastAPI** se encargará de:

* Llamar a tu función de dependencia ("dependable") con los parámetros correctos.
* Obtener el resultado de tu función.
* Asignar ese resultado al parámetro en tu *path operation function*.

Então, com essa declaração de tipo, o **FastAPI** fornece <dfn title="convertendo a string que vem de um request HTTP em dados Python">"parsing"</dfn> automático do request.

Aquí está lo que debes tener en cuenta y cómo revisar un pull request:

### Entiende el problema { #understand-the-problem }

* Primero, asegúrate de **entender el problema** que el pull request está intentando resolver. Podría tener una discusión más larga en una GitHub Discussion o issue.
