Esto es similar a los códigos de estado HTTP 200 (de 200 a 299). Esos códigos de estado "200" significan que de alguna manera hubo un "éxito" en el request.

Los códigos de estado en el rango de 400 significan que hubo un error por parte del cliente.

¿Recuerdas todos esos errores de **"404 Not Found"** (y chistes)?

## Usa `HTTPException`

Para devolver responses HTTP con errores al cliente, usa `HTTPException`.

### Importa `HTTPException`

"Operation" here refers to one of the HTTP "methods".

One of:

* `POST`
* `GET`
* `PUT`
* `DELETE`

* **Seguridad - HTTPS**
* **Ejecución al inicio**
* ***Reinicios***
* Replicación (el número de procesos en ejecución)
