13.8. Chapter Assessment

Create a tuple called olympics with four elements: “Beijing”, “London”, “Rio”, “Tokyo”.

==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(olympics, ('Beijing', 'London', 'Rio', 'Tokyo'), "Testing that olympics is assigned to correct values") myTests().main()

The list below, tuples_lst, is a list of tuples. Create a list of the second elements of each tuple and assign this list to the variable country.

tuples_lst = [('Beijing', 'China', 2008), ('London', 'England', 2012), ('Rio', 'Brazil', 2016, 'Current'), ('Tokyo', 'Japan', 2020, 'Future')] ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testTwo(self): self.assertEqual(country, ['China', 'England', 'Brazil', 'Japan'], "Testing that third is assigned to correct values") myTests().main()

With only one line of code, assign the variables city, country, and year to the values of the tuple olymp.

olymp = ('Rio', 'Brazil', 2016) ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testThree(self): self.assertEqual(city, "Rio", "Testing that city is assigned to correct value.") self.assertEqual(country, "Brazil", "Testing that country is assigned to correct value.") self.assertEqual(year, 2016, "Testing that year is assigned to correct value.") myTests().main()

Define a function called info with five parameters: name, gender, age, bday_month, and hometown. The function should then return a tuple with all five parameters in that order.

==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testFour(self): self.assertEqual(info("Sue", "Female", 20, "March", "Ann Arbor"), ("Sue", "Female", 20, "March", "Ann Arbor"), "Testing that info('Sue', 'Female', 20, 'March', 'Ann Arbor') returns('Sue', 'Female', 20, 'March', 'Ann Arbor')") myTests().main()

Given is the dictionary, gold, which shows the country and the number of gold medals they have earned so far in the 2016 Olympics. Create a list, num_medals, that contains only the number of medals for each country. You must use the .items() method. Note: The .items() method provides a list of tuples. Do not use .keys() method.

gold = {'USA':31, 'Great Britain':19, 'China':19, 'Germany':13, 'Russia':12, 'Japan':10, 'France':8, 'Italy':8} ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testFive(self): self.assertEqual(sorted(num_medals), sorted([31, 19, 19, 13, 12, 10, 8, 8]), "Testing that num_medals is assigned to correct values.") self.assertNotIn('.keys()', self.getEditorText(), "Testing your code (Don't worry about actual and expected values).") self.assertIn('.items()', self.getEditorText(), "Testing your code (Don't worry about actual and expected values).") self.assertNotIn('in gold:', self.getEditorText(), "Testing your code (Don't worry about actual and expected values).") myTests().main()
