I should have included some code that does this: """ from __future__ import division import psyco psyco.full() fofx = raw_input("What is the function? ") minimum = raw_input("What is the minimum? ") maximum = raw_input("What is the maximum? ") start = time.time() minimum = float(minimum) maximum = float(maximum) total = 0 step = 100000 x = minimum a = compile(fofx, '<string>', 'eval') while minimum <= x <= maximum: area = eval(a)/step total = total+area x = x+1/step print total """ This takes ~1.7 seconds here, so about 8 times faster than without the compile() call, but about 2.5 times slower than directly with the 3*x*x. =Tony.Meyer _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
