With the help of Numpy numpy.ndarray.__mul__(), we can multiply a particular value that is provided as a parameter in the ndarray.__mul__() method. Value will be multiplied to each and every element in a numpy array.
Syntax: ndarray.__mul__($self, value, /)
Return: self*value
Example #1 :
In this example, we can see that each element in an array is multiplied with the value given as a parameter in method ndarray.__mul__(). This method will work fine for positive, negative and floating point values of an array.
# import the important module in python import numpy as np    # make an array with numpy gfg = np.array([1, 2.5, 3, 4.8, 5])    # applying ndarray.__mul__() method print(gfg.__mul__(5)) |
Output:
[ 5. 12.5 15. 24. 25. ]
Example #2 :
# import the important module in python import numpy as np    # make an array with numpy gfg = np.array([[1, 2, 3, 4.45, 5],                 [6, 5.5, 4, 3, 2.62]])    # applying ndarray.__mul__() method print(gfg.__mul__(5)) |
Output:
[[ 5. 10. 15. 22.25 25. ] [ 30. 27.5 20. 15. 13.1 ]]
