Hi, I have the following list: l = [1, 2, 3, 4] and I'd like to obtain a list like the following: l_partial_sum = [1, 3, 6, 10] (that is [1, 1+2, 1+2+3, 1+2+3+4])
Is there a simple way to accomplish this? I came up with the following solution but it seems a bit too elaborated for the task: l_partial_sum = [reduce(lambda x,y:x+y, sub_l) for sub_l in [l[:i+1] for i in range(len(l))]] Any help will be appreciated.
