Python | numpy.assert_allclose() method

With the help of numpy.assert_allclose() method, we can get the assertion errors when two array objects are not equal upto the mark by using numpy.assert_allclose().

Syntax : numpy.assert_allclose(actual_array, desired_array)

Return : Return the Assertion error if two array objects are not equal.

Example #1 :
In this example we can see that using numpy.assert_allclose() method, we are able to get the assertion error if two arrays are not equal.

# import numpy
import numpy as np

# using numpy.assert_allclose() method
gfg1 = [1, 2, 3]
gfg2 = np.array(gfg1)

if np.testing.assert_allclose(gfg1, gfg2):
     print("Matched")

Output :

Matched

Example #2 :

# import numpy
import numpy as np

# using numpy.assert_allclose() method
gfg1 = [1, 2, 3]
gfg2 = np.array([4, 5, 6])

print(np.testing.assert_allclose(gfg1, gfg2))

Output :

Mismatch: 100%
Max absolute difference: 3
Max relative difference: 0.75
gfg1: array([1, 2, 3])
gfg2: array([4, 5, 6])
