# Body - Multiple Parameters

Now that we have seen how to use `Path` and `Query`, let's see more advanced uses of request body declarations.

## Mix `Path`, `Query` and body parameters

First, of course, you can mix `Path`, `Query` and request body parameter declarations freely and **FastAPI** will know what to do.

And you can also declare body parameters as optional, by setting the default to `None`:

#### Utiliser votre FastAPI local

Si vous créez un fichier Python qui importe et utilise FastAPI, et que vous l'exécutez avec le Python de votre environnement local, il utilisera votre code source FastAPI local.

Et si vous mettez à jour le code source local de FastAPI, tel qu'il est installé avec `--symlink` (ou `--pth-file` sous Windows), lorsque vous exécutez à nouveau ce fichier Python, il utilisera la nouvelle version de FastAPI que vous venez d'éditer.
