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 numpy as np
gfg = np.array([1, 2, 3, 4, 5])
print(gfg.__sub__(5))
|
Example #2 :
import numpy as np
gfg = np.array([[1, 2, 3, 4, 5],
[6, 5, 4, 3, 2]])
print(gfg.__sub__(5))
|
Output:
[[-4 -3 -2 -1 0]
[ 1 0 -1 -2 -3]]
