여러분은 벌써 API를 만들었습니다:

* _경로_ `/` 및 `/items/{item_id}`에서 HTTP 요청 받기.
* 두 _경로_ 모두 `GET` 연산(HTTP _메소드_ 로 알려진)을 받습니다.
* _경로_ `/items/{item_id}`는 `int`형 이어야 하는 _경로 매개변수_ `item_id`를 가지고 있습니다.

@app.get("/items/", operation_id="some_specific_id_you_define")
async def read_items():

{* ../../docs_src/python_types/tutorial007_py310.py hl[1] *}

Das bedeutet:

* Die Variable `items_t` ist ein `tuple` mit 3 Elementen, einem `int`, einem weiteren `int` und einem `str`.
* Die Variable `items_s` ist ein `set`, und jedes seiner Elemente ist vom Typ `bytes`.
