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 6の解答を求めてみる。

コード

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

temps = [25.2, 16.8, 31.4, 23.9, 28, 22.5, 19.6]
cool_temps = None
warm_temps = None


class MyTestCase(TestCase):
    def test_b(self):
        temps.sort()
        self.assertEqual(temps, [16.8, 19.6, 22.5, 23.9, 25.2, 28, 31.4])

    def test_c(self):
        global cool_temps, warm_temps
        cool_temps = temps[:2]
        warm_temps = temps[2:]
        self.assertEqual(cool_temps, [16.8, 19.6])
        self.assertEqual(warm_temps, [22.5, 23.9, 25.2, 28, 31.4])

    def test_d(self):
        global cool_temps, warm_temps
        temps_in_celsius = cool_temps + warm_temps
        self.assertEqual(temps_in_celsius, temps)


if __name__ == '__main__':
    main()

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

% ./sample6.py -v
test_b (__main__.MyTestCase) ... ok
test_c (__main__.MyTestCase) ... ok
test_d (__main__.MyTestCase) ... ok
