lets say you have this column of numbers 1000028706 1000028707 1000028708 100 12 1000028706 1000028707 1000028708 1000028709 1000028706 1000028707 1000028708 100 12 6 How can I build up a program that tells me that this sequence 1000028706 1000028707 1000028708 is repeated somewhere in the column, and how can i know where? thank you very much! -- http://mail.python.org/mailman/listinfo/python-list
