I recently installed Python 2.7.3 on a CentOS machine by compiling from source. Python 2.7.3 is installed at /opt/python2.7 and when I installed it I just changed /usr/bin/p
Put /opt/python2.7/bin in your PATH environment variable in front of /usr/bin...or just get used to typing python2.7.
/opt/python2.7/bin
PATH
/usr/bin
python2.7
