コード

Python 3

#!/usr/bin/env python3
from unittest import TestCase, main

kingdoms = ['Bacteria', 'Protozoa',
            'Chromista', 'Plantae', 'Fungi', 'Animalia']


class MyTestCase(TestCase):
    def test(self):
        spam = [kingdoms[-6], kingdoms[-1],
                kingdoms[:-3], kingdoms[-4:-1], kingdoms[-2:], kingdoms[-1:-2]]
        egg = ['Bacteria', 'Animalia', ['Bacteria', 'Protozoa', 'Chromista'], ['Chromista', 'Plantae', 'Fungi'],
               ['Fungi', 'Animalia'], []]
        for s, t in zip(spam, egg):
            self.assertEqual(s, t)


if __name__ == '__main__':
    main()
