* `DELETE` : pour supprimer de la donnée.

Donc, dans **OpenAPI**, chaque méthode HTTP est appelée une "opération".

Nous allons donc aussi appeler ces dernières des "**opérations**".

## Faites appel à `uvicorn`

Dans votre application FastAPI, importez et exécutez directement `uvicorn` :

{* ../../docs_src/debugging/tutorial001.py hl[1,15] *}

### À propos de `__name__ == "__main__"`

Le but principal de `__name__ == "__main__"` est d'avoir du code qui est exécuté lorsque votre fichier est appelé avec :

<div class="termy">

```console
$ python myapp.py

# Object Lock and Immutablity Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO server allows WORM for specific objects or by configuring a bucket with default object lock configuration that applies default retention mode and retention duration to all objects. This makes objects in the bucket immutable i.e. delete of the version are not allowed until an expiry specified in the bucket's object lock configuration or object retention.
