For example, a product:
>>> [prev * k for k in [5, 2, 4, 3] from prev = 1]
[1, 5, 10, 40, 120]
That makes sense for me, and seem simpler than:
>>> from itertools import accumulate, chain
>>> list(accumulate(chain([1], [5, 2, 4, 3]), lambda prev, k: prev * k))
[1, 5, 10, 40, 120]
Well, if you want an instant reaction from someone skimming this thread:
I looked at the first example and couldn't understand it. Then I looked
at the second one, and could understand it (even though I may never have
used "chain" or heard of "accumulate"). Obviously your mileage varies.
