Python | Numpy np.assert_array_less() method Last Updated : 23 Jan, 2020 Comments Improve Suggest changes Like Article Like Report 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. Python3 1=1 # 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 : Python3 1=1 # 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 Comment More infoAdvertise with us Next Article Python | Numpy np.assert_array_less() method J Jitender_1998 Follow Improve Article Tags : Python Python-numpy Python numpy-Testing Practice Tags : python Similar Reads Python | Numpy np.assert_array_equal() method With the help of np.assert_array_equal() method, we can get the assertion error if two array like objects are not equal by using np.assert_array_equal() method.
