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.

Syntax : np.assert_array_equal(x, y)
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_equal() method, we are able to get the assertion error if two error like objects are not equal by using this method.

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

# using np.assert_array_equal() method
gfg = npt.assert_array_equal([1.22, 0.22], [1.22, 0.22])

print(gfg)

Output :

None

Example #2 :

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

# using np.assert_array_equal() method
gfg = npt.assert_array_equal([1.22, 1.22], [2.22, 0.22])

print(gfg)

Output :

AssertionError:
Arrays are not equal

Mismatch: 100%
Max absolute difference: 1.
Max relative difference: 4.54545455
x: array([1.22, 1.22])
y: array([2.22, 0.22])
