It mostly depends on what sort of thing you're learning Python for.

If you have a project in mind that has large dependencies that still
require Python 2.x, then you're probably best off with 2.x for now.

Otherwise, go with 3.x.

Or do what I've been enjoying: Install 2.x and 3.x, and test with
both, each step of the way.  In this manner, you can pretty easily
write new code that runs on either equally well.  But again, there's
the matter of dependencies.
