Python | Numpy numpy.ndarray.__isub__()
  • Last Updated : 11 Mar, 2019

With the help of numpy.ndarray.__isub__() method, we can subtract a particular value that is provided as a parameter in the ndarray.__isub__() method. Value will be subtracted to every element in a numpy array.

Syntax: ndarray.__isub__($self, value, /)

Return: self-=value

Example #1 :
In this example we can see that each and every element in an array is subtracted with the value given as a parameter in method ndarray.__isub__(). Remember this method will work with every type of numeric value.




# import the important module in python
import numpy as np
    
# make an array with numpy
gfg = np.array([1.2, 2.6, 3, 4.5, 5])
    
# applying ndarray.__isub__() method
print(gfg.__isub__(5))


Output:



[-3.8 -2.4 -2.  -0.5  0. ]

Example #2 :




# import the important module in python
import numpy as np
    
# make an array with numpy
gfg = np.array([[1, 2.2, 3, 4, 5.01],
                [6.1, 5, 4.8, 3, 2]])
    
# applying ndarray.__isub__() method
print(gfg.__isub__(3))


Output:

[[-2.   -0.8   0.    1.    2.01]
 [ 3.1   2.    1.8   0.   -1.  ]]
