<summary>Ya da <code>async def</code>...</summary>

Eğer kodunuzda `async` / `await` varsa, `async def` kullanalım:

```Python hl_lines="9  14"

        {"detail": exc.detail}, status_code=exc.status_code, headers=headers
    )


async def request_validation_exception_handler(
    request: Request, exc: RequestValidationError
) -> JSONResponse:
    return JSONResponse(
        status_code=422,
        content={"detail": jsonable_encoder(exc.errors())},
    )


async def websocket_request_validation_exception_handler(

def test_get_items():
    response = client.get("/items/")
    assert response.status_code == 200, response.text
    assert response.json() == ["Portal gun", "Plumbus"]

    response = client.get("/users/")
    assert response.status_code == 200, response.text

Это обычная функция, которая может принимать параметры.

Это может быть как `async def`, так и обычная функция `def`, **FastAPI** знает, как корректно её выполнить.

В этом случае функция задачи будет записывать данные в файл (имитируя отправку письма).

Так как операция записи не использует `async` и `await`, мы определим функцию как обычную `def`:
