## L'ordre importe

Quand vous créez des *fonctions de chemins*, vous pouvez vous retrouver dans une situation où vous avez un chemin fixe.

Tel que `/users/me`, disons pour récupérer les données sur l'utilisateur actuel.

Et vous avez un second chemin : `/users/{user_id}` pour récupérer de la donnée sur un utilisateur spécifique grâce à son identifiant d'utilisateur

conversation.  While she was trying to fix on one, the cook took
the cauldron of soup off the fire, and at once set to work
throwing everything within her reach at the Duchess and the baby
--the fire-irons came first; then followed a shower of saucepans,
plates, and dishes.  The Duchess took no notice of them even when
they hit her; and the baby was howling so much already, that it

## Code asynchrone

Faire du code asynchrone signifie que le langage 💬 est capable de dire à l'ordinateur / au programme 🤖 qu'à un moment du code, il 🤖 devra attendre que *quelque chose d'autre* se termine autre part. Disons que ce *quelque chose d'autre* est appelé "fichier-lent" 📝.

Donc, pendant ce temps, l'ordinateur pourra effectuer d'autres tâches, pendant que "fichier-lent" 📝 se termine.

textarea.form-control {\n    @include form-validation-state-selector($state) {\n      @if $enable-validation-icons {\n        padding-right: $input-height-inner;\n        background-position: top $input-height-inner-quarter right $input-height-inner-quarter;\n      }\n    }\n  }\n\n  .custom-select {\n    @include form-validation-state-selector($state) {\n      border-color: $color;\n\n      @if $enable-validation-icons {\n        padding-right: $custom-select-feedback-icon-padding-right;\n        background: $...

Hasta ahora, escasamente vimos lo básico pero ya tienes una idea de cómo funciona.

Intenta cambiando la línea a:

```Python
    return {"item_name": item.name, "item_id": item_id}

Par exemple, disons que vous voulez avoir un *chemin d'accès* qui permet de mettre à jour les éléments et renvoie les codes HTTP 200 "OK" en cas de succès.
