Lecture 4 Exercises¶

Assign the number of elements in lst to the variable output. lst = ["hi", "morning", "dog", "506", "caterpillar", "balloons", 106, "yo-yo", "python", "moon", "water", "sleepy", "daffy", 45, "donald", "whiteboard", "glasses", "markers", "couches", "butterfly", "100", "magazine", "door", "picture", "window", ["Olympics", "handle"], "chair", "pages", "readings", "burger", "juggle", "craft", ["store", "poster", "board"], "laptop", "computer", "plates", "hotdog", "salad", "backpack", "zipper", "ring", "watch", "finger", "bags", "boxes", "pods", "peas", "apples", "horse", "guinea pig", "bowl", "EECS"] ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testTwo(self): self.assertEqual(output, 52, "Testing that output value is assigned to correct value.") myTests().main()

Assign the last element of lst to the variable end_elem. Do this so that it works no matter how long lst is. lst = ["hi", "goodbye", "python", "106", "506", 91, ['all', 'Paul', 'Jackie', "UMSI", 1, "Stephen", 4.5], 109, "chair", "pizza", "wolverine", 2017, 3.92, 1817, "account", "readings", "papers", 12, "facebook", "twitter", 193.2, "snapchat", "leaders and the best", "social", "1986", 9, 29, "holiday", ["women", "olympics", "gold", "rio", 21, "2016", "men"], "26trombones"] ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(end_elem, lst[-1], "Testing that end_elem has the correct element assigned.") myTests().main()

Create a new list that contains the 6th through 13th (as humans count) elements of lst (eight items in all) and assign it to the variable output. lst = ["swimming", 2, "water bottle", 44, "lollipop", "shine", "marsh", "winter", "donkey", "rain", ["Rio", "Beijing", "London"], [1,2,3], "gold", "bronze", "silver", "mathematician", "scientist", "actor", "actress", "win", "cell phone", "leg", "running", "horse", "socket", "plug", ["Phelps", "le Clos", "Lochte"], "drink", 22, "happyfeet", "penguins"] ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testFour(self): self.assertEqual(output, lst[5:13], "Testing that output value is assigned to correct value.") myTests().main()

Assign the 4th element of s (as humans count) to the variable a. Do not hard code – use indexing!

Then assign the 7th (again, as humans count) element of s to the variable b. Do not hard code – use indexing!

s = "supercalifragilisticexpialidocious" ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testFive(self): self.assertEqual(a, s[3], "Testing value of a.") self.assertEqual(b, s[6], "Testing value of b.") myTests().main()
