Voici notre "**fonction de chemin**" (ou fonction d'opération de chemin) :

* **chemin** : `/`.
* **opération** : `get`.
* **fonction** : la fonction sous le "décorateur" (sous `@app.get("/")`).

C'est une fonction Python.

Elle sera appelée par **FastAPI** quand une requête sur l'URL `/` sera reçue via une opération `GET`.

 * Allows providing standard input that can be consumed by the gradle operation (useful for interactive builds).
