Com `async def`, o Python sabe que, dentro dessa função, ele deve estar ciente das expressões `await`, e que isso poderá "pausar" ⏸ a execução dessa função, e ir fazer outra coisa 🔀 antes de voltar.

Quando você quiser chamar uma função `async def`, você tem que "esperar" ela. Então, isso não funcionará:

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

E a especificação diz que os campos devem ser nomeados assim. Portanto, `user-name` ou `email` não funcionariam.

Mas não se preocupe, você pode mostrá-lo como quiser aos usuários finais no frontend.

E seus modelos de banco de dados podem usar qualquer outro nome que você desejar.
