Correction: checking the Library Reference, I find that this is wrong. The reason is that file objects implement their own read-ahead buffer, and mixing calls to next() and readline() may not work right. See http://docs.python.org/lib/bltin-file-objects.html Replace the fp.readline() with fp.next() and all should be good. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
