Notice that the variable `item` is one of the elements in the list `items`.

And still, the editor knows it is a `str`, and provides support for that.

#### Tuple and Set

You would do the same to declare `tuple`s and `set`s:

from typing import Dict, List, Tuple

import pytest
from fastapi import FastAPI
from pydantic import BaseModel


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

        class Item(BaseModel):
            title: str

        @app.get("/items/{id}")
        def read_items(id: List[Item]):
            pass  # pragma: no cover


def test_invalid_tuple():

from typing import Set, Tuple


def process_items(items_t: Tuple[int, int, str], items_s: Set[bytes]):

      eventListener.requestFailed(call, e)
      trackFailure(e)
      throw e
    }
  }

  @Throws(IOException::class)
  fun createRequestBody(
    request: Request,
    duplex: Boolean,
  ): Sink {
    this.isDuplex = duplex
    val contentLength = request.body!!.contentLength()
    eventListener.requestBodyStart(call)
    val rawRequestBody = codec.createRequestBody(request, contentLength)

* `list`
* `tuple`
* `set`
* `dict`

Verwenden Sie für den Rest, wie unter Python 3.8, das `typing`-Modul:

* `Union`
* `Optional`
* ... und andere.

* `List`
* `Tuple`

* `Dict`
* `Union`

Chú ý rằng, biến `item` là một trong các phần tử trong danh sách `items`.

Và do vậy, trình soạn thảo biết nó là một `str`, và cung cấp sự hỗ trợ cho nó.

#### Tuple and Set

Bạn sẽ làm điều tương tự để khai báo các `tuple` và  các `set`:

#### `Tuple` ve `Set`

`Tuple` ve `set`lerin tiplerini bildirmek için de aynısını yapıyoruz:

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

Bu şu anlama geliyor:

* `items_t` değişkeni sırasıyla `int`, `int`, ve `str` tiplerinden oluşan bir `tuple` türündedir .
* `items_s` ise her öğesi `bytes` türünde olan bir `set` örneğidir.

    AnyUrl: str,
