## `async` and `await`

Modern versions of Python have a very intuitive way to define asynchronous code. This makes it look just like normal "sequential" code and do the "awaiting" for you at the right moments.

When there is an operation that will require waiting before giving the results and has support for these new Python features, you can code it like:

```Python
burgers = await get_burgers(2)
```

Comme il est très simple, son apprentissage est relativement intuitif, bien que la documentation soit quelque peu
technique par moments.

    return burgers
```

### Mais detalhes técnicos

Você deve ter observado que `await` pode ser usado somente dentro de funções definidas com `async def`.

Mas ao mesmo tempo, funções definidas com `async def` tem que ser aguardadas. Então, funções com `async def` pdem ser chamadas somente dentro de funções definidas com `async def` também.

Então, sobre o ovo e a galinha, como você chama a primeira função async?

## Código Asíncrono

El código asíncrono sólo significa que el lenguaje 💬 tiene una manera de decirle al sistema / programa 🤖 que, en algún momento del código, 🤖 tendrá que esperar a que *algo más* termine en otro sitio. Digamos que ese *algo más* se llama, por ejemplo, "archivo lento" 📝.

Durante ese tiempo, el sistema puede hacer otras cosas, mientras "archivo lento" 📝 termina.

Jusqu'au moment où c'est (enfin) votre tour. Vous allez au comptoir, récupérez vos burgers 🍔 et revenez à votre table.
