Aquí, la función manejadora del evento `shutdown` escribirá una línea de texto `"Application shutdown"` a un archivo `log.txt`.

/// info | Información

En la función `open()`, el `mode="a"` significa "añadir", por lo tanto, la línea será añadida después de lo que sea que esté en ese archivo, sin sobrescribir el contenido anterior.
