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.

if you.want(clear_syntax) and you.want(almost_everything()) and you.is_elegant():
    you.use(python)
else:
    grass.feed_with([ kill(cellule) for cellule in you if cellule.is_alive()])
