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?

Your hint was subtler (and probably more intelligent) than mine. You're right, I think I overdid it, but the sudden influx of /g/ users is worrying (and annoying) me. I mean, even the past influx of /b/ users were moderately better than this.

Anyway, sorry if I was being a faggot. Carry on, good sir.
