[CentralOH] Installing Python on Linux from Source?

[Max]

For Enterprise Linux distros, you can generally find packages using
rpmfind.net.  Some are put together by less well known packagers, so please
be careful.  The IUS repo is probably your best bet if you're not on fedora
to get the latest upstream packages from a reliable team and not breaking
namespaces.

For ubuntu, 16.10 and above have python3.6 packaged and ready.  If you're
on an older version (which is a reasonable guess), you can get all versions
through 3.5.1 from this repo:
https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes.  Alas, the
maintainer ran out of time to be able to support this.  As I tend to run a
lot more on enterprise linux... I really can't recommend much else.

An alternative is to switch to using anaconda (once they upgrade, they are
slower as they have a *lot* of stuff to maintain and test).  This works
cross-platform (windows, mac, most varieties of linux) and is highly
recommended if your sysadmin skills aren't strong.
