/// tip | Consejo

Pydantic tiene un comportamiento especial cuando utilizas `Optional` o `Union[Something, None]` sin un valor por defecto, puedes leer más sobre ello en la documentación de Pydantic sobre <a href="https://docs.pydantic.dev/2.3/usage/models/#required-fields" class="external-link" target="_blank">Required Optional fields</a>.

/// tip

Pydantic یه رفتار خاص داره وقتی از `Optional` یا `Union[Something, None]` بدون مقدار پیش‌فرض استفاده می‌کنی، می‌تونی توی مستندات Pydantic در مورد <a href="https://docs.pydantic.dev/2.3/usage/models/#required-fields" class="external-link" target="_blank">فیلدهای اختیاری لازم</a> بیشتر بخونی.

---

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
```
