[codeup] python 기초 100제 풀이

 

 

최근 간단한 사이트 하나를 장고로 개발해서 배포까지 한 적이 있습니다.

 

그간 Java와 Javascript만 써왔던 저지만 Django가 어드민 페이지를 기본으로 제공해주는 프레임워크라고 하니 개발 시간을 단축할 수 있겠다 싶어 내린 선택이었는데

 

Python 문법을 검색하며 코드를 짜다보니 Python이 제가 그간 사용해 온 다른 언어들에 비해서 코드를 짧게 짜기에 굉장히 수월하더라고요.

 

그 매력에 빠져서 python을 본격적으로 써볼까 싶어 문법 연습 겸 코딩 테스트 연습 겸 해서 python 코드업 100제를 풀어봤습니다.

 

나름대로는 최대한 pythonic하게 풀어보려 한건데 아직 부족한 점이 많을 것 같아 포스팅으로 올려봅니다.

더 좋은 방법 댓글로 남겨주시면 감사히 배우겠습니다! 많은 첨언 부탁드려요
