... and precalculate that in the setup: python -m timeit -s "loops=tuple(range(100))" "sum([x * x * 1 for x in loops])" # python -m timeit "sum([x * x * 1 for x in range(100)])" 100000 loops, best of 3: 5.74 usec per loop # python -m timeit -s "loops=tuple(range(100))" "sum([x * x * 1 for x in loops])" 100000 loops, best of 3: 5.56 usec per loop (python = Python 2.7) -- Marc-Andre Lemburg eGenix.com _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
