Python | Numpy MaskedArray.lshift

0 0 1 minute read

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.

   
# 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:

# 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))
