`@lru_cache` is part of `functools` which is part of Python's standard library, you can read more about it in the <a href="https://docs.python.org/3/library/functools.html#functools.lru_cache" class="external-link" target="_blank">Python docs for `@lru_cache`</a>.

이 예전 OpenAPI-특화 `examples` 매개변수는 이제 FastAPI `0.103.0`부터 `openapi_examples`입니다.

### JSON 스키마의 `examples` 필드

하지만, 후에 JSON 스키마는 <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>필드를 명세서의 새 버전에 추가했습니다.

그리고 새로운 OpenAPI 3.1.0은 이 새로운 `examples` 필드가 포함된 최신 버전 (JSON 스키마 2020-12)을 기반으로 했습니다.

`@lru_cache` es parte de `functools`, que es parte del paquete estándar de Python, puedes leer más sobre él en las <a href="https://docs.python.org/3/library/functools.html#functools.lru_cache" class="external-link" target="_blank">docs de Python para `@lru_cache`</a>.

## Resumen { #recap }

가장 중요한 건, 표준 파이썬 타입을 한 곳에서(클래스를 더하거나, 데코레이터 사용하는 대신) 사용함으로써 **FastAPI**가 당신을 위해 많은 일을 해준다는 사실이죠.

/// info | 정보

만약 모든 자습서를 다 보았음에도 타입에 대해서 더 보고자 방문한 경우에는 <a href="https://mypy.readthedocs.io/en/latest/cheat_sheet_py3.html" class="external-link" target="_blank">`mypy`에서 제공하는 "cheat sheet"</a>이 좋은 자료가 될 겁니다.
