I don't know, I'm not able to replicate the problem you're reporting. When I try your script with a value of 150000, it runs in under a second and does not appear to consume any more virtual memory than what is normally used by the Python interpreter. I suspect there is something else at play here. > What would be a better way to do this? (aside from checking arg > values and types, I know...) I don't see anything wrong with the way you're currently doing it, assuming you can solve your memory leak issue. Ian -- http://mail.python.org/mailman/listinfo/python-list
