Huh??? There is only a very slight resemblance to the code that you
posted previously ... both contain 'max, 'i', and 'j'

I suggest that you don't bother reading a blog written by somebody who
(presumably consciously) keyed in that "if w[i-1] <= j: " above.

Oh, very interesting, it contains:
def msum(a):
    return max([(sum(a[j:i]), (j,i)) for i in range(1,len(a)+1) for j
in range(i)])

Would you care to tell us which part of which function you are now
trying to understand?
