[uemy] python 부트캠프 _ section 15 _로컬 개발 환경 설정과 커피머신

01. 파이참의 매력 포인트

• spell check
• More space
• built-in Linter : 지정된 코딩 스타일에 맞지 않는 코드를 골라냄.
• Local History : 지난 12시간 동안 진행한 코드들을 확인할 수 있다.
• View Structure : 코드의 모든 변수와 함수가 분류되어 수백 줄이 넘는 긴 코드에서 쉽게 함수,변수를 찾을 수 있다.
• Refactor Rename : 변수나 함수의 이름을 변경하고 싶을 때, 한 꺼번에 자동으로 고쳐줌. refactor -> rename 한번에 고칠 수 있음.
