/** Adapt OkHttp's internal [Http2Stream] type to the public [Stream] type. */

Observe que a variável `item` é um dos elementos da lista `items`.

E, ainda assim, o editor sabe que é um `str` e fornece suporte para isso.

#### Tuple e Set

Você faria o mesmo para declarar `tuple`s e `set`s:

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial007_py39.py!}
```

import pytest
from fastapi import FastAPI, Query
from pydantic import BaseModel


def test_invalid_sequence():
    with pytest.raises(AssertionError):
        app = FastAPI()

        class Item(BaseModel):
            title: str

        @app.get("/items/")
        def read_items(q: List[Item] = Query(default=None)):
            pass  # pragma: no cover

И все же редактор знает, что это `str`, и поддерживает это.

#### `Tuple` и `Set`

Вы бы сделали то же самое, чтобы объявить `tuple` и `set`:

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial007.py!}
```

Это означает:

* Переменная `items_t` является `tuple` с 3 элементами: `int`, другим `int` и `str`.
