To be really honest, if you want to run it as "smooth as possible" you'll
NEED numpy anyway. If you have an algoritmn of any significant mathematical
complexity, numpy's Fortran implementation will beat out pure python
easily. I don't have any experience with monte carlo simulations myself,
but if you're doing this any significant amount of times you'll be better
off creating a numpy array.

And personally I just grab Anaconda. It knows how to install wherever, and
includes numpy and a lot of other things you might need. If you want it
smooth, for beginners, that'd be my first recommendation. (Actually, I
started using it because I had trouble installing numpy stack on a new
system back when I was a noob.) Most students learning python will probably
be on windows, so just down loading an installer and clicking through it
should be more than familiar for them.
