Vous écrivez le premier paramètre, `first_name`, puis un point (`.`) et appuyez sur `Ctrl+Espace` pour déclencher l'auto-complétion.

Mais malheureusement, rien d'utile n'en résulte :

### Ajouter des types

Modifions une seule ligne de la version précédente.

Nous allons changer seulement cet extrait, les paramètres de la fonction, de :

		totalInodes:       "Total inodes on a drive",
		cpuUser:           "CPU user time",
		cpuSystem:         "CPU system time",
		cpuIdle:           "CPU idle time",
		cpuIOWait:         "CPU ioWait time",
		cpuSteal:          "CPU steal time",
		cpuNice:           "CPU nice time",
		cpuLoad1:          "CPU load average 1min",
		cpuLoad5:          "CPU load average 5min",
		cpuLoad15:         "CPU load average 15min",

    Donc, avec ces mêmes déclarations de type Python, **FastAPI** vous fournit de la validation de données.

    Notez que l'erreur mentionne le point exact où la validation n'a pas réussi.

    Ce qui est incroyablement utile au moment de développer et débugger du code qui interagit avec votre API.
