For the correct way to time operations, see the timeit module. For your specific problem, it is hard to tell what you are doing wrong when you don't tell us what "datafile" is. What's "outfile" for? It gets created *after* the command runs, but doesn't get used. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
