Python | Numpy numpy.ndarray .__ sub __ ()



With Numpy numpy.ndarray .__ sub __ () we can subtract a specific value that is provided as a parameter in ndarray .__ sub __ () . The value will be subtracted for each item in the numpy array .

Syntax: ndarray .__ sub __ ($ self, value, /)

Return: self-value

Example # 1:
In this example, we see that each element the array is subtracted with the value specified as a parameter in the ndarray .__ sub __ () method. Remember one thing, this will not work for double values.

# import important module into python

import numpy as np

 
# make an array with NumPy

gfg = np.array ([ 1 , 2 , 3 , 4 , 5 ] )

 
# applying the ndarray method .__ sub __ ()

 print (gfg .__ sub __ ( 5 ))

Exit:

 [-4 -3 -2 - 1 0] 

Example # 2:

# import important module into python

import numpy as np

 
# make an array with NumPy

gfg = np.array ([[ 1 , 2 , 3 , 4 , 5 ],

  [ 6 , 5 , 4 , 3 , 2 ] ])

 
# applying the ndarray method .__ sub __ ()

print (gfg .__ sub __ ( 5 ))

Output:

 [[-4 -3 -2 -1 0] [1 0 -1 -2 -3]]
