As Wolfgang says -- dunno why the 4 (my code below works for 3) And I wonder whether you are making us do your homework. Still heres something to start you off def row(max,n): return range(2*n-1, max+n) def tri(max): return [row(max,i) for i in range(1,max+1)] >>> tri(3) [[1, 2, 3], [3, 4], [5]] >>> -- http://mail.python.org/mailman/listinfo/python-list
