Lecture 8 Exercises¶

The dictionary Junior shows a schedule for a junior year semester. The key is the course name and the value is the number of credits. Find the total number of credits taken this semester and assign it to the variable credits. Do not hardcode this – use dictionary accumulation! courses = {'SI 206':4, 'SI 310':4, 'BL 300':3, 'TO 313':3, 'BCOM 350':1, 'MO 300':3} ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(credits, 18, "Testing that credits is assigned to correct values") myTests().main()

Create a dictionary, freq, that displays each letter in string str1 as the key and the number of times it occurs in the string as the value. str1 = "peter piper picked a peck of pickled peppers" ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testTwo(self): self.assertEqual(sorted(freq.items()), sorted([(' ', 7), ('a', 1), ('c', 3), ('d', 2), ('e', 8), ('f', 1), ('i', 3), ('k', 3), ('l', 1), ('o', 1), ('p', 9), ('r', 3), ('s', 1), ('t', 1)]), "Testing that freq is correct.") myTests().main()
