commended.

You are about to remove system-level python $major binaries
and dependencies.
Uninstalling a Python version you have installed using this
program generally works fine. Please note that uninstalling
a Python version included natively with your operating
system is ${ul}not recommended${reset}.
Depending on your Linux distribution, some operating system
functions may depend upon the Python version(s) included
natively with the OS.
Although the uninstall functionality has been successfully
tested on all supported major Linux distributions,

# sudo yum -y update
# # install epel
# curl -o epel.rpm https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
