## Особые типы и валидация

Помимо обычных простых типов, таких как `str`, `int`, `float`, и т.д. Вы можете использовать более сложные базовые типы, которые наследуются от типа `str`.

여기서 그 경우를 볼 것입니다.

이 경우, `float` 값을 가진 `int` 키가 있는 모든 `dict`를 받아들입니다:

/// tip | 팁

JSON은 오직 `str`형 키만 지원한다는 것을 염두에 두세요.

하지만 Pydantic은 자동 데이터 변환이 있습니다.

즉, API 클라이언트가 문자열을 키로 보내더라도 해당 문자열이 순수한 정수를 포함하는한 Pydantic은 이를 변환하고 검증합니다.

그러므로 `weights`로 받은 `dict`는 실제로 `int` 키와 `float` 값을 가집니다.
