Why not use a dictionary instead of two lists? Then you can sort the dictionary by value -- e.g. d = dict(zip(items, values)) sorted_items = sorted(d.iteritems(), key=lambda (k,v): (v,k)) This produces a list of pairs, but demonstrates the general idea. -- http://mail.python.org/mailman/listinfo/python-list
