I am stuck with installing python2.7 on my redhat6 , which has default python 2.6 installed. Also searched a lot for repository of 'python-deltarpm' and 'deltarpm' which is required for installing 'createrepo', but didn't get. I added repo from dvd and from https://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/ and yum repolist gives repolist: 11,960. I want to install pip & virtualenv using python2.7.
Got it...I installed python2.7 as follows
cd /usr/src
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar xzf Python-2.7.13.tgz
cd Python-2.7.13
./configure
make altinstall
