With the help of Numpy numpy.ndarray.__sub__(), We can subtract a particular value that is provided as a parameter in the ndarray.__sub__() method. Value will be subtracted to each and every element in a numpy array.
Syntax: ndarray.__sub__($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.__sub__(). Remember one thing it wouldn’t work for double type values.
# import the important module in python import numpy as np # make an array with numpy gfg = np.array([1, 2, 3, 4, 5]) # applying ndarray.__sub__() method print(gfg.__sub__(5)) |
Output:
[-4 -3 -2 -1 0]
Example #2 :
# import the important module in python import numpy as np # make an array with numpy gfg = np.array([[1, 2, 3, 4, 5], [6, 5, 4, 3, 2]]) # applying ndarray.__sub__() method print(gfg.__sub__(5)) |
Output:
[[-4 -3 -2 -1 0] [ 1 0 -1 -2 -3]]
