# numpy.testing.assert_equal

testing.assert_equal(actual, desired, err_msg='', verbose=True)

  Raises an AssertionError if two objects are not equal.

  Given two objects (scalars, lists, tuples, dictionaries or numpy arrays), check that all elements of these objects are equal. An exception is raised at the first conflicting values.

  When one of actual and desired is a scalar and the other is array_like, the function checks that each element of the array_like object is equal to the scalar.

  This function handles NaN comparisons as if NaN was a “normal” number. That is, AssertionError is not raised if both objects have NaNs in the same positions. This is in contrast to the IEEE standard on NaNs, which says that NaN compared to anything must return False.

  Parameters
    actual array_like

      The object to check.

    desired array_like

      The expected object.

    err_msg str, optional

      The error message to be printed in case of failure.

    verbose bool, optional

      If True, the conflicting values are appended to the error message.

  Raises
    AssertionError

      If actual and desired are not equal.

  Examples

      >>> np.testing.assert_equal([4,5], [4,6])
      Traceback (most recent call last):
          ...
      AssertionError:
      Items are not equal:
      item=1
       ACTUAL: 5
       DESIRED: 6

  The following comparison does not raise an exception. There are NaNs in the inputs, but they are in the same positions.

      >>> np.testing.assert_equal(np.array([1.0, 2.0, np.nan]), [1, 2, np.nan])
