and given that the files are huge, a little bit of preprocessing wouldn't go astray: initially: valid_8 = set(['N', 'P']) valid_6 = set(['0', '1']) then for each record: if fields[8] in valid_8 and fields[6] in valid_6: More meaningful names wouldn't go astray either :-) -- http://mail.python.org/mailman/listinfo/python-list
