Yes thats why Chris said the linear loop solution is almost 
certainly faster in this case. However you could speed up 
the for loop significantly by missing out the call to 

>>> for x in d:
>>>        y += x
>>>        dd.append(y)

Should give the same result...

List Comprehensions are not always the best answer.
