numpy.ma.MaskedArray class is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__eq__ operator we can find that which element in an array is equal to the value which is provided in the parameter.

Syntax: numpy.MaskedArray.__eq__

Return: self==value

Example #1 :
In this example we can see that after applying MaskedArray.__eq__(), we get the simple boolean array that can tell us which element in an array is equal that of provided parameter.




# 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]) 
  
# applying MaskedArray.__eq__() method 
print(gfg.__eq__(4)) 


Output:

[False False False  True False False]

 
Example #2:




# 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], 
                [6, 5, 4, 3, 2, 1]]) 
  
# applying MaskedArray.__eq__() method 
print(gfg.__eq__(4)) 


Output:

[[False False False  True False False]
 [False False  True False False False]]
