You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

Et comme type, mettez `List`.

Les listes étant un type contenant des types internes, mettez ces derniers entre crochets (`[`, `]`) :
