For CentOS, I recommend using either an SCL
(https://www.softwarecollections.org/en/scls/rhscl/rh-python36/) or
perhaps Anaconda.

Installing Python 3 with an SCL is nice because it's managed through
your package manager, but is completely independent of the system Python
(so it won't break anything). You have to enable it on a case-by-case
basis when you want to use it, which can be a bit finicky.
