You have *path operations* for:

* `/items/`
* `/items/{item_id}`

It's all the same structure as with `app/routers/users.py`.

But we want to be smarter and simplify the code a bit.

We know all the *path operations* in this module have the same:

* Path `prefix`: `/items`.
* `tags`: (just one tag: `items`).
* Extra `responses`.

Le mot-clé important ici est `await`. Il informe Python qu'il faut attendre ⏸ que `get_burgers(2)` finisse d'effectuer ses opérations 🕙 avant de stocker les résultats dans la variable `burgers`. Grâce à cela, Python saura qu'il peut aller effectuer d'autres opérations 🔀 ⏯ pendant ce temps (comme par exemple recevoir une autre requête).
