Also, The first one should be sum(x*x for x in xrange(10)) >>> def f1(): return sum([x*x for x in range(1,10)]) ... >>> def f2(): return sum([x*x for x in xrange(1,10)]) ... >>> def f3(): return sum(x*x for x in xrange(1,10)) ... >>> import timeit >>> timeit.timeit(f1, number = 100000) 0.20368003845214844 >>> timeit.timeit(f2, number = 100000) 0.17799496650695801 >>> timeit.timeit(f3, number = 100000) 0.17561507225036621 [...] -- ~noufal http://nibrahim.net.in I must follow the people.
