### Déclarer une `list` avec un paramètre de type { #declare-a-list-with-a-type-parameter }

Pour déclarer des types qui ont des paramètres de type (types internes), comme `list`, `dict`, `tuple`,
passez le(s) type(s) interne(s) comme « paramètres de type » à l'aide de crochets : `[` et `]`

```Python
my_list: list[str]
```

C'est simplement la syntaxe Python standard pour les déclarations de type.

To add it to your *path operation*, declare it the same way you declared path and query parameters:

{* ../../docs_src/body/tutorial001_py310.py hl[16] *}

...and declare its type as the model you created, `Item`.

## Results { #results }

With just that Python type declaration, **FastAPI** will:

* Read the body of the request as JSON.
* Convert the corresponding types (if needed).
* Validate the data.
