Opinion on Python Security Books

[phread]

I just asked about this the other day. I've got my GPEN and I'm trying to learn to script in Python, but you're right, all of the most recent pen test books reference 2.7. It's because Kali hasn't updated and is pre-loaded with 2.7.13-2 which apparently all of the tools that use it are written for. Kind of an annoying position to be in as a new guy to Python. Everyone on here said to learn 3.x, so it's a conundrum.
