Upgrade Python from 2.6 to 2.7 on Centos 6.5

Put the below line in ~/.bashrc file:

alias python=/usr/local/bin/python2.7

Now execute the command:

source ~/.bashrc

Now type python to check which version it has mapped to. It maps to Python2.7.

I can't add comment yet, only answer: Centos relies on python 2.6 for yum. You may break your system and yum if switching to 2.7 globally.
