# Status Codes

You can import the `status` module from `fastapi`:

```python
from fastapi import status
```

`status` is provided directly by Starlette.

It contains a group of named constants (variables) with integer status codes.

For example:

* 200: `status.HTTP_200_OK`
* 403: `status.HTTP_403_FORBIDDEN`
* etc.

Pour y parvenir, importez `JSONResponse` et renvoyez-y directement votre contenu, en définissant le `status_code` que vous souhaitez :

```Python hl_lines="4 25"
{!../../../docs_src/additional_status_codes/tutorial001.py!}
```

!!! warning "Attention"
    Lorsque vous renvoyez une `Response` directement, comme dans l'exemple ci-dessus, elle sera renvoyée directement.
