Python Install tag - Voyager of Linux

최근에 발표된 CentOS 7 에서는 Python 2.7.5 버전이 설치되어 있습니다. 하지만 CentOS 6.x 버전에서는 Python 2.6 버전이 설치되어 있어서 2.7 버전 소스 설치에 대해 정리했습니다. Python 2.7 은 Python 2,x 대의 마지막 버전이 될 것입니다. 현재 Python 3.x 가 최신이지만 Python 2.x 대도 여전히 많이 쓰이고 모듈도 많이 있어서 지금도 많이 쓰입니다. 특히나 Python 2.7 은 다음과 같은 기능상의 변화가 있었습니다.

Updated module: The io library has been upgraded to the version shipped with Python 3.1. For 3.1, 
the I/O library was entirely rewritten in C and is 2 to 20 times faster depending on the task being performed. 
The original Python version was renamed to the _pyio module.
