Lisp Vs. Python

I am looking to learn another programming language, I am a bit of a newbie but I know C, Java, and C++ rather well and am looking to expand.

I am interested in AI so I am considering Lisp.
But I also hear python is on the rise so I am considering that.

Which should I choose and why?

New people usually come from /g/, and that's not an indicator of good posting quality.

I'm worried about it because people like you usually shit up the place.
