...isso também inclui o `uvicorn`, que você pode usar como o servidor que rodará seu código.

!!! note "Nota"
    Você também pode instalar parte por parte.

    Isso é provavelmente o que você faria quando você quisesse lançar sua aplicação em produção:

    ```
    pip install fastapi
    ```

    Também instale o `uvicorn` para funcionar como servidor:

    ```
    pip install "uvicorn[standard]"
    ```

// An example of good use of a Pool is in the fmt package, which maintains a

// On the other hand, a free list maintained as part of a short-lived object is
// not a suitable use for a Pool, since the overhead does not amortize well in

Luego, cuando llega tu turno, haces un trabajo "productivo" real 🤓, procesas el menú, decides lo que quieres, lo que quiere esa persona 😍, pagas 💸, verificas que das el billete o tarjeta correctos, verificas que te cobren correctamente, que el pedido tiene los artículos correctos, etc.
