Notice how we write `CommonQueryParams` twice in the above code:

//// tab | Python 3.9+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.9+ non-Annotated

/// tip

Prefer to use the `Annotated` version if possible.

///

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

////

Perceba como escrevemos `CommonQueryParams` duas vezes no código abaixo:

//// tab | Python 3.9+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.9+ non-Annotated

/// tip | Dica

Utilize a versão com `Annotated` se possível.

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)

### Імпорт `Query` та `Annotated`

Щоб це зробити, спочатку імпортуємо:

* `Query` з `fastapi`
* `Annotated` з `typing`

{* ../../docs_src/query_params_str_validations/tutorial002_an_py310.py hl[1,3] *}

/// info | Інформація

FastAPI додав підтримку `Annotated` (і почав рекомендувати його) у версії 0.95.0.

Якщо у Вас старіша версія, під час використання `Annotated` можуть виникати помилки.

O FastAPI adicionou suporte a `Annotated` (e passou a recomendá-lo) na versão 0.95.0.

Se você tiver uma versão mais antiga, verá erros ao tentar usar `Annotated`.
