Here's two ways. First makes a copy, second flattens each list in place, both assume it's the last member (at index -1) of the list that needs flattening. datami = [ ['46295', 'Montauk', '3', '60', '85', ['19', '5', '1', '0 $277790.00']], ['46295', 'Dark Eyes', '5', '59', '83', ['6', '4', '1', '0 $105625.00']], ['46295', 'Machinegun Jubs', '6', '53', '77', ['6', '2', '1', '1 $71685.00']], ['46295', 'Zara Bay', '1', '53', '77', ['12', '2', '3', '3 $112645.00']]] flat = [ data[:-1] + data[-1] for data in datami ] for data in datami: data.extend(data.pop()) print('flat copy of datami:', *flat, sep = '\n') print('flattened datami:', *datami, sep = '\n') -- https://mail.python.org/mailman/listinfo/python-list
