Thank you Chris. That will set me on my path.

Unfortunately Ubuntu based distros are going through a 2.x to 3.x
transition period. Both Pythons are installed and are system dependencies.

And their finicky dependency on Python really make these distros not
very friendly for Python development. If I do end up successfully
upgrading from 3.4 to 3.5, I will most likely forfeit my ability to
upgrade the Mint version in the future without a full system
installation. So the solution is to just maintain 3 different versions
of python my machine. Ridiculous.
