The problem is this:  performing addition of tuples is concatenation,
not addition of the elements.  If you try to decompose the augmented
addition into an addition and an assignment, you get a tuple that is
(in your case) the concatenation of the two 3-tuples, or a 6-tuple,
which can't unpack into a 3-tuple.

That said, for some definition of "cleaner", you could do:
def accumulate(i,j):
    return map(int.__add__, i, j)

// loop
    i,j,k = accumulate((i,j,k), fn())
