PrettyTable은 아름다운 ASCII 형식을 생성하는 데 사용할 수 있는 Python의 타사 라이브러리입니다 양식 은 매우 실용적입니다.
다음은 공식 소개입니다.
표 형식의 데이터를 시각적으로 매력적인 ASCII 표 형식으로 쉽게 표시하는 간단한 Python 라이브러리
를 지정하여 "하위 테이블" 인쇄.
. PrettyTable은 시각적으로 매력적인 ASCII 테이블에서 테이블 형식 데이터를 빠르고 쉽게 표현할 수 있도록 설계된 간단한 Python 라이브러리입니다. PostgreSQL 셸 psql에서 사용되는 ASCII 테이블에서 영감을 받아 인쇄할 열을 선택할 수 있습니다. , 열의 독립적인 정렬(왼쪽 또는 오른쪽 정렬 또는 가운데 정렬) 및 행 범위
