numpy.ma.MaskedArray class is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__rmul__ we can multiply a particular value that is provided as a parameter in the MaskedArray.__rmul__() method.
Syntax: numpy.MaskedArray.__rmul__ Return: Multiply others by self, 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.__rmul__(). 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.__rmul__() method 
print(gfg.__rmul__(3))
Output: 
[ 3  6  9 12 15]
  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.__rmul__() method 
print(gfg.__rmul__(5))
Output: 
[[ 5 10 15 20 25]
 [30 25 20 15 10]]
