If you want a normal distribution, using the Box-Muller transform is
simpler because it spares you the complication of figuring out whether
the 12-trial binomial approximation is close enough to produce reliable
results for your specific application, which you obviously have to do if
you are using the approximation for anything serious. It also involves
writing less code than that list comprehension, since it is already
implemented in the random module so you can just call it directly.
