In this tutorial we will install Python 3.6, 3.7, 3.8 & 3.9 on CentOS 7. The default python version in CentOS 7 is 2.7.5. If we forcefully upgrade or replace this version, yum and other utitiles may break causing the OS to become unstable.
Instead of upgrading/replacing default python, we will install the new version of python using alternate install method. This setup will also install corresponding pip for each python version separately.
