Numpy cumulative product

import numpy as np

arr = np.array([[6, 1, 3], [8, 2, 1]])

print(‘2D Array\n’,arr)

b = np.cumprod(arr, dtype=int)

print(‘Cumulative product of all elements\n’,b)

c = np.cumprod(arr,axis=0)

print(‘Cumulative product of elements axis=0\n’,c)

x = np.array([6, 1, 3])

print(‘Single dimension array ‘,x)

y = np.cumprod(x, dtype=int)
