Ensuite, lorsque vous créez une instance de cette classe `Settings` (dans ce cas, l'objet `settings`), Pydantic lira les variables d'environnement de manière insensible à la casse, donc une variable en majuscules `APP_NAME` sera tout de même lue pour l'attribut `app_name`.

Of course, there are some cases where there's no problem in running the previous steps multiple times, in that case, it's a lot easier to handle.

Also, keep in mind that depending on your setup, in some cases you **might not even need any previous steps** before starting your application.

In that case, you wouldn't have to worry about any of this. 🤷
