@MartijnPieters the accepted answer in the dupe seems to yield a different result from what OP wants. — timgeb, Feb 10 '16 at 12:14
@MartijnPieters For OP's list im getting `[1, 102, 41, 61, 6, 55, 1, 54, 41, 13]`. What and where should I skip? — timgeb, Feb 10 '16 at 12:17
@timgeb: the second answer, using `accumulate()`. So `islice(accumulate(input_list), 1, None))`, to include skipping the first result. — Martijn Pieters, Feb 10 '16 at 12:18
@MartijnPieters yeah, ok, I'm only questioning that this question is a dupe of that other one. The OP in the dupe seems to desire a completely different output. — timgeb, Feb 10 '16 at 12:22

With numpy.cumsum:

>>> import numpy as np
>>> lst = [1, 41, 6, 1, 41, 13]
>>> list(np.cumsum(lst)[1:])
[42, 48, 49, 90, 103]
