For hosts with firewall-cmd enabled (CentOS), you can use `firewall-cmd` command to allow traffic to specific ports. Use below commands to allow access to port 9000

```sh
firewall-cmd --get-active-zones
```

This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use

```sh
firewall-cmd --zone=public --add-port=9000/tcp --permanent
```

Entonces, pruebas con el amigo del viejo programador, el autocompletado del editor.

Escribes el primer parámetro de la función, `first_name`, luego un punto (`.`) y luego presionas `Ctrl+Espacio` para activar el autocompletado.

Pero, tristemente, no obtienes nada útil:
