Practical Programming: An Introduction to Computer Science Using Python 3.6 (Paul Gries(著)、Jennifer Campbell(著)、Jason Montojo(著)、Pragmatic Bookshelf)のChapter 8(Storing Collections of Data Using Lists)、Exercise 10の解答を求めてみる。

コード

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

units = [['km', 'miles', 'league'],
         ['kg', 'pound', 'stone']]


class MyTestCase(TestCase):
    def test_a(self):
        self.assertEqual(units[0], ['km', 'miles', 'league'])

    def test_b(self):
        self.assertEqual(units[len(units) - 1], ['kg', 'pound', 'stone'])

    def test_c(self):
        self.assertEqual(units[0][0], 'km')

    def test_d(self):
        self.assertEqual(units[1][0], 'kg')

    def test_e(self):
        self.assertEqual(units[0][1:], ['miles', 'league'])

    def test_f(self):
        self.assertEqual(units[1][:2], ['kg', 'pound'])


if __name__ == '__main__':
    main()

入出力結果(Zsh、cmd.exe(コマンドプロンプト)、Terminal、Jupyter(IPython))
