Hi, depending on the specification, the tests could be e.g.: results = [[[1, 5, 11], [2, 6, 7], [3, 4, 8]], [[1, 6, 8], [2, 4, 9], [3, 5, 7]]] #testing for the sum 1..9 - this would also pass for some "paired" repeated items, which most likely isn't indended print all(sum((elem for sublist in result for elem in sublist))==45 for result in results) # testing for different items without repeating - not only 1..9 print all(len(set(elem for sublist in result for elem in sublist))==9 for result in results) # testing explicitely for items 0..9 in any order print all((set(elem for sublist in result for elem in sublist))==set([1,2,3,4,5,6,7,8,9]) for result in results) hth, vbr -- https://mail.python.org/mailman/listinfo/python-list
