#### Burgers parallèles

Imaginons désormais que ce ne sont pas des "burgers concurrents" mais des "burgers parallèles".

```Python
# Isso não irá funcionar, porquê get_burgers foi definido com: async def
burgers = get_burgers(2)
```

Então, se você está usando uma biblioteca que diz que você pode chamá-la com `await`, você precisa criar as *funções de operação de rota* com `async def`, como em:

```Python hl_lines="2 3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```
