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