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` { #use-httpexception }

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

### Importa `HTTPException` { #import-httpexception }
