[PyQt4] 0x03. QYolk I

Python package 중에는 Yolk라고 하는 것이 있다.

이 사이트에 설명이 되어 있는데

자신의 시스템에 설치된 PyPI(Python Package Index)를 관리할 수 있는 툴이다.

보다시피 커맨드라인 기반 툴이기 때문에 GUI로는 볼 수 없는데, 이를 Qt로 GUI화한 것이 QYolk이다.

사실 이미 만들어져 있는 툴이기는 하다. (https://www.linux-apps.com/content/show.php/QYolk?content=107046)

처음엔 일단 List로 현재 설치된 package와 그 버전, 상태를 보도록 했다.

우선 pip install yolk 를 통해 yolk를 설치해야 하고, 파이썬 내에서 yolklib을 가져와서 사용한다.

++ 2016.11.18

- Yolk 라이브러리를 https://pypi.python.org/pypi/yolk3k 로 업데이트하면서 함수를 일부 변경하였습니다.
