=== Default Python version is 2.6.6 === CentOS 6 must have 2.6.6 as main install because of some system applications that depend on it. === Newer versions === Newer versions of Python are available in ''/share/apps/python/''. To use these version, add the desired version's path to your search path, or call the binaries directly. Or you can use the Software Collections ''scl'' tool. Run ''scl -l'' for a list of installed collections. Then, e.g., to use Python 2.7, run this: scl enable python27 bash This will start a new shell that's set to use python 2.7 (run ''which python'' and ''python --version'' to verify).
