Des changements sur Pydantic ont même été faits pour supporter cela.

Les captures d'écran précédentes ont été prises sur [Visual Studio Code](https://code.visualstudio.com).

Mais vous auriez le même support de l'éditeur avec [PyCharm](https://www.jetbrains.com/pycharm/) et la majorité des autres éditeurs de code Python :

Mais, malheureusement, vous n'obtenez rien d'utile :

### Ajouter des types { #add-types }

Modifions une seule ligne de la version précédente.

Nous allons changer exactement ce fragment, les paramètres de la fonction, de :

```Python
    first_name, last_name
```

à :

```Python
    first_name: str, last_name: str
```

        else -> JavaNetSocket(route.proxy)

    // Handle the race where cancel() precedes connectSocket(). We don't want to miss a cancel.

## Créer une dépendance de base de données avec `yield` { #a-database-dependency-with-yield }

Par exemple, vous pouvez l'utiliser pour créer une session de base de données et la fermer après la fin.

Seul le code précédant et incluant l'instruction `yield` est exécuté avant la création de la réponse :

{* ../../docs_src/dependencies/tutorial007_py310.py hl[2:4] *}

And then the new OpenAPI 3.1.0 was based on the latest version (JSON Schema 2020-12) that included this new field `examples`.

And now this new `examples` field takes precedence over the old single (and custom) `example` field, that is now deprecated.

This new `examples` field in JSON Schema is **just a `list`** of examples, not a dict with extra metadata as in the other places in OpenAPI (described above).
