Hi, Looking through the archives, it looks like some recommend reading the file into a list and doing it that way. And if they file is too big, than use a database. See links below: http://mail.python.org/pipermail/tutor/2006-March/045571.html http://mail.python.org/pipermail/tutor/2006-March/045572.html I also found this interesting idea that explains what would be needed to accomplish this task: http://mail.python.org/pipermail/python-list/2001-April/076890.html Have fun!
