I'll also note that one of the things we (and others) *have* been putting quite a bit of time into is the question of "Why do people avoid using extension modules for code acceleration?".
well, the scientific computing community does do that a lot -- with f2py, Cyton, and more recently numba. But the current state of the art makes it fairly easy and practical for number crunching (and to a somewhat less extent basic text crunching), but not so much for manipulating higher order data structures. For example running the OPs code through Cython would likely buy you very little performance. I don't think numba would do much for you either (though I don't have real experience with that) PyPy is the only one I know of that is targeting general "Python" code per se. -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
