NumPy.diff()

import numpy as np
x = np.array([1, 2, 4, 7, 0])
print( np.diff(x) )      # [ 1  2  3 -7]
print( np.diff(x, n=2) ) # [  1   1 -10]

import numpy as np
x = np.array([[1, 3, 6, 10], [0, 5, 6, 8]])
print( np.diff(x) ) # [[2 3 4]
                    #  [5 1 2]]
print( np.diff(x, axis=0) ) # [[-1  2  0 -2]]

import numpy as np
x = np.arange('1066-10-13', '1066-10-16', dtype=np.datetime64)
print( np.diff(x) )
