numpy.ma.MaskedArray class is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__iand__we can get the elements that is anded by the value that is provided as a parameter in the MaskedArray.__iand__() method.
Syntax: numpy.MaskedArray.__iand__($self, value, /) Return: Return self&=value.
Example #1 : In this example we can see that every element is anded by the value that is passed as a parameter in MaskedArray.__iand__() method. 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.__iand__() method 
print(gfg.__iand__(2)) 
 
Output:
[0 2 2 0 0]
  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.__iand__() method 
print(gfg.__iand__(1)) 
Output:
[[1 0 1 0 1]
 [0 1 0 1 0]]
