**FastAPI** proporciona los mismos `starlette.responses` como `fastapi.responses` solo como una conveniencia para ti, el desarrollador. Pero la mayoría de los responses disponibles vienen directamente de Starlette.

Y como el `Response` se puede usar frecuentemente para establecer headers y cookies, **FastAPI** también lo proporciona en `fastapi.Response`.

## Eine virtuelle Umgebung erstellen { #create-a-virtual-environment }

Après avoir activé l’environnement virtuel, la variable `PATH` ressemblerait à quelque chose comme ceci :

//// tab | Linux, macOS

```plaintext
/home/user/code/awesome-project/.venv/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

Cela signifie que le système commencera maintenant par chercher des programmes dans :

```plaintext
/home/user/code/awesome-project/.venv/bin
```

avant de chercher dans les autres répertoires.
