/// note | Detalles Técnicos

También podrías usar `from starlette.responses import JSONResponse`.

**FastAPI** proporciona los mismos `starlette.responses` que `fastapi.responses` solo como una conveniencia para ti, el desarrollador. Pero la mayoría de los responses disponibles provienen directamente de Starlette. Lo mismo con `status`.

Обратите внимание на значение `3`, которое получила (и вернула) функция. Это целочисленный Python `int`, а не строка `"3"`.

Используя такое объявление типов, **FastAPI** выполняет автоматический <abbr title="преобразование строк из HTTP-запроса в типы данных Python">"парсинг"</abbr> запросов.
