Thanks Sounds like you want to read up on itertools.combinations() and the sum() function. http://docs.python.org/library/itertools.html#itertools.combinations or >>> import itertools >>> help(itertools.combinations) This sounds like a homework problem, so I won't hand you the answer, but you pass your list to combinations() with the grouping-size (r). You then iterate over the results of that, and use sum() on the results. -tkc
