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. Best wishes, Rob Cliffe
