numpy.ma.MaskedArray class is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__lshift__ method we can get the elements that is left shifted by the value that is provided as a parameter.
Syntax: numpy.MaskedArray.__lshift__ Return: Return self<<value.
Example #1 : In this example we can see that every element is left shifted by the value that is passed as a parameter. 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.__lshift__() method 
print(gfg.__lshift__(2)) 
Output:
[ 4  8 12 16 20]
  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.__lshift__() method 
print(gfg.__lshift__(1)) 
Output:
[[ 2  4  6  8 10]
 [12 10  8  6  4]]
