Это обычная функция, которая может принимать параметры.

Это может быть как `async def`, так и обычная функция `def`, **FastAPI** знает, как корректно её выполнить.

В этом случае функция задачи будет записывать данные в файл (имитируя отправку письма).

Так как операция записи не использует `async` и `await`, мы определим функцию как обычную `def`:

    * Si on compare Starlette, il faut le comparer à d'autres frameworks web (ou micorframework) comme Sanic, Flask, Django, etc.
* **FastAPI** :
    * Comme Starlette, FastAPI utilise Uvicorn et ne peut donc pas être plus rapide que ce dernier.
