python - Perform a reverse cumulative sum on a numpy array -


can recommend way reverse cumulative sum on numpy array?

where 'reverse cumulative sum' defined below (i welcome corrections on name procedure):

if

x = np.array([0,1,2,3,4])

then

np.cumsum(x)

gives

array([0,1,3,6,10])

however, get

array([10,10,9,7,4]

can suggest way this?

this it:

np.cumsum(x[::-1])[::-1]
