Sum slices of consecutive values in a NumPy array

Question

Let\'s say I have a numpy array a containing 10 values. Just an example situation here, although I would like to repeat the same for an array with length 100.

Answer 1

You could use

import numpy as np

a = np.array([1,2,3,4,5,6,7,8,9,10])
step = 5

for i in range(0,a.shape[0],step):
    print(np.sum(a[i:i+step]))
