You might also put the outer loop calling function advance so many
times, into the advance function:
def advance(bodies, dt, n) :
for i in xrange(n) :
for i,b in enumerate(bodies) :
def main() :
advance(bodies, 0.01, n)
This I like. It points to areas of python where maybe we should be
adding to the standard library whilst also showing off the cream of the
non-standard libraries out their.
