단순한 우연이 아닙니다. 프레임워크 전체가 이러한 디자인을 중심으로 설계되었습니다.

그 어떤 실행 전에, 모든 편집기에서 작동할 수 있도록 보장하기 위해 설계 단계에서 혹독하게 테스트되었습니다.

이를 지원하기 위해 Pydantic 자체에서 몇몇 변경점이 있었습니다.

이전 스크린샷은 <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>를 찍은 것입니다.

하지만 똑같은 편집기 지원을 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>에서 받을 수 있거나, 대부분의 다른 편집기에서도 받을 수 있습니다:

`@app.get("/")` mówi **FastAPI** że funkcja poniżej odpowiada za obsługę żądań, które trafiają do:

/// info | `@decorator` Info

Składnia `@something` jest w Pythonie nazywana "dekoratorem".

Umieszczasz to na szczycie funkcji. Jak ładną ozdobną czapkę (chyba stąd wzięła się nazwa).
