책소개
4차산업혁명에서는 컴퓨터 소프트웨어의 중요성이 더욱 커질 것으로 예상되며,
모든 업무에서 인공지능 기술이 가장 핵심적인 요소로 등극하게 될 것이다. 이에
따라 대학교는 물론 초중고등학교에서도 컴퓨터 프로그래밍 교육의 중요성이 커지
며, 교육과정에서 수업 시간도 점차 많아지고 있다. 현재 모든 사람들이 컴퓨터와
스마트폰을 사용하듯이 미래에는 모든 사람들이 프로그램을 작성하고, 이를 바탕으
로 업무를 수행할 것이다.
이 책은 기존 파이썬 프로그래밍 책과는 다르게 중학교 수준 정도의 기초 수학을
알면 프로그램을 작성할 수 있도록 구성하였다. 다른 책들이 언어의 문법을 주로
설명하였다면, 이 책에서는 순차, 조건, 반복, 함수 등의 개념을 쉽게 이해할 수 있
고, 응용할 수 있도록 구성하였다. 이 책의 접근 방법은 고등학생 및 대학 신입생
교양 수업 등에서 이공계는 물론 인문사회 분야 학생들에게 적용해보았으며, 학생들
의 만족도가 기존 다른 책들에 비해 매우 높았다.
이 책을 통해서 독자들이 프로그래밍에 대한 이해와 파이썬 언어의 기초를 배울
수 있기를 희망한다.
