Scripting

Hi, i'm a sophomore in college and i'm going to start learning a scripting language.  Which one should i learn?  I hear ruby and python a lot, but also i hear lua is on par with them, and i think if it truly is on par i'd like to learn lua.

from languages import strange, elegant
from prog import TipicalProgGuy
from sky import God
from river import Cocodrile

def decide(you, code);
    satisfaction = [not you.like('()' * 100 and code.full_of('()')), max(code.portability), max(code.modules), max(code.oo)]

    if all(satisfaction):
        return you.use(elegant.python)
    elif any(satisfaction) and you.are(TipicalProgGuy):
        return you.use(strange.lisp)
    else:
        god = God('An intelligent one please!')
        cocodriles = [Cocodrile()] * 100
        return god.kill(you) and god.gives(you, cocodriles)
