Python | Numpy MaskedArray.__mul__ Last Updated : 27 Mar, 2019 Comments Improve Suggest changes Like Article Like Report numpy.ma.MaskedArray class is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__mul__ we can multiply a particular value that is provided as a parameter in the MaskedArray.__mul__() method. Syntax: numpy.MaskedArray.__mul__ Return: Multiply self by other, and return a new masked array. 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 MaskedArray.__mul__(). Python3 1== # import the important module in python import numpy as np # make an array with numpy gfg = np.ma.array([1, 2, 3, 4, 5]) # applying MaskedArray.__mul__() method print(gfg.__mul__(5)) Output: [ 5 10 15 20 25] Example #2: Python3 1== # import the important module in python import numpy as np # make an array with numpy gfg = np.ma.array([[1, 2, 3, 4, 5], [6, 5, 4, 3, 2]]) # applying MaskedArray.__mul__() method print(gfg.__mul__(5)) Output: [[ 5 10 15 20 25] [30 25 20 15 10]] Comment More infoAdvertise with us Next Article Python | Numpy MaskedArray.__mul__ S Shivam_k Follow Improve Article Tags : Python Python-numpy Python numpy-ndarray Practice Tags : python Similar Reads Python | Numpy MaskedArray.__mod__ What is a mask?
