With the help of numpy.ndarray.__lt__() method of Numpy, We can find that which element in an array is less than the value which is provided in the parameter. It will return you numpy array with boolean type having only values True and False.

Syntax: ndarray.__lt__($self, value, /) Return: self<value

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

Python3




# import the important module in python
import numpy as np
 
# make an array with numpy
gfg = np.array([1, 2, 3, 4, 5, 6])
 
# applying numpy.__lt__() method
print(gfg.__lt__(4))


Output:

[True True True False False False]

Example #2 : 

Python3




# import the important module in python
import numpy as np
 
# make an array with numpy
gfg = np.array([[1, 2, 3, 4, 5, 6],
                [6, 5, 4, 3, 2, 1]])
 
# applying numpy.__lt__() method
print(gfg.__lt__(4))


Output:

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