AFAIK, only if you try to have too many files open at one time -- many appears to be approx 512 on recent Windows (2000 and XP at least). However it's a very good habit whatever the language to close / delete / deallocate / ... any resource as soon as you no longer need it. -- http://mail.python.org/mailman/listinfo/python-list
