In RedHat Enterprise Linux 8, Python doesn't come preinstalled. The main reason for this is that the RHEL 8 developers didn't want to set a default Python version for users. Therefore as a RHEL user, you need to specify whether you want Python 3 or 2 by installing it. In addition, in RHEL, Python 3.6 is the default and fully supported version of Python. However, Python 2 remains available and you can install it.
