Hi, I have a csv file: 'aaa.111', 'T100', 'pn123', 'sn111' 'aaa.111', 'T200', 'pn123', 'sn222' 'bbb.333', 'T300', 'pn123', 'sn333' 'ccc.444', 'T400', 'pn123', 'sn444' 'ddd', 'T500', 'pn123', 'sn555' 'eee.666', 'T600', 'pn123', 'sn444' 'fff.777', 'T700', 'pn123', 'sn777'
How can I extract duplicates checking each row by filed1 and filed4? I should get something like that: 'aaa.111', 'T100', 'pn123', 'sn111' 'bbb.333', 'T300', 'pn123', 'sn333' 'ccc.444', 'T400', 'pn123', 'sn444' 'ddd', 'T500', 'pn123', 'sn555' 'fff.777', 'T700', 'pn123', 'sn777' and 'aaa.111', 'T200', 'pn123', 'sn222' 'eee.666', 'T600', 'pn123', 'sn444' Any help will be extremely appreciated. -- http://mail.python.org/mailman/listinfo/python-list
