Actually here in my code ['1', 'a', '6'], ['1', 'b', '6'], ['1', 'c', '6'] means: 1==> Directory name; a,b,c,d=== Filename 6 ==> modified time So i want the out put like: Directory name: 1 Filename:a modified time:6 Filename:b modified time:6 Filename:c modified time:6 and so on.......... -- http://mail.python.org/mailman/listinfo/python-list
