Python | Numpy MaskedArray.__lshift__

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))

Output:

[[ 2  4  6  8 10]
 [12 10  8  6  4]]
