Python | Numpy numpy.ndarray.imul() (original) (raw)

Last Updated : 22 Jul, 2021

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

Syntax: ndarray.__imul__($self, value, /)
Return: self*=value

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

Python3

import numpy as np

gfg = np.array([ 1.2 , 2.6 , 3 , 4.5 , 5 ])

print (gfg.__imul__( 5 ))

Output:

[ 6. 13. 15. 22.5 25. ]

Example #2 :

Python3

import numpy as np

gfg = np.array([[ 1 , 2.2 , 3 , 4 , 5.01 ],

`` [ 6.1 , 5 , 4.8 , 3 , 2 ]])

print (gfg.__imul__( 3 ))

Output:

[[ 3. 6.6 9. 12. 15.03] [ 18.3 15. 14.4 9. 6. ]]
