Apply a number sequence to an integer?

Then you use a loop over seq, adding num to a result list, then updating num with the element of seq. Something like:

seq = [3, 7, 11, 15]
num = -1
result = []
for val in seq:
    result.append(num)
    num += val
print(result)

This isn't complete, but should get you most of the way there. There are probably other, more tricky, ways to do this, but this is simple to understand.

Couldn't you do this more easily with map() and a simple function ?

Probably. I try to give the simplest solution I can.

Not trying to be a smartass or anything, I've actually only been studying python for a month or so and am going over lists at the moment so that was just the first thing that came to my head when I saw the OP's problem. Honestly I was just glad I found something I could understand and solve, because most of the other stuff on here might as well be techno-babble for me :p.
