Python | Numpy numpy.ndarray.__isub__()
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 numpy as np
gfg = np.array([ 1.2 , 2.6 , 3 , 4.5 , 5 ])
print (gfg.__isub__( 5 ))
|
Output:
[-3.8 -2.4 -2. -0.5 0. ]
Example #2 :
import numpy as np
gfg = np.array([[ 1 , 2.2 , 3 , 4 , 5.01 ],
[ 6.1 , 5 , 4.8 , 3 , 2 ]])
print (gfg.__isub__( 3 ))
|
Output:
[[-2. -0.8 0. 1. 2.01]
[ 3.1 2. 1.8 0. -1. ]]
