Python | Numpy np.assert_array_less() method

With the help of np.assert_array_less() method, we can get the assertion error if two array like objects are not ordered by less than by using np.assert_array_less() method.

Syntax : np.assert_array_less(x, y)
Return : Return assertion error if two array objects are unequal.

Example #1 :
In this example we can see that by using np.assert_array_less() method, we are able to get the assertion error if two array like objects are not equal by less than by using this method.

# import numpy and assert_array_less
import numpy as np
import numpy.testing as npt

# using np.assert_array_less() method
gfg = npt.assert_array_less([3, 4], [1, 2])

print(gfg)

Output :

AssertionError:
Arrays are not less-ordered

Mismatch: 100%
Max absolute difference: 2
Max relative difference: 2.
x: array([3, 4])
y: array([1, 2])

Example #2 :

# import numpy and assert_array_less
import numpy as np
import numpy.testing as npt

# using np.assert_array_less() method
gfg = npt.assert_array_less([0.1, 1], [1, 2])

print(gfg)

Output :

None
