Python | Numpy np.assert_array_almost_equal() method Last Updated : 23 Jan, 2020 Comments Improve Suggest changes Like Article Like Report With the help of np.assert_array_almost_equal() method, we can get the assertion error if two array objects are not equal up to desired precision value by using np.assert_array_almost_equal() method. Syntax : np.assert_array_almost_equal(actual, desired, decimal) Return : Return the assertion error if two objects are not equal. Example #1 : In this example we can see that by using np.assert_array_almost_equal() method, we are able to get the assertion error if two array objects are not equal by using this method.
