Lecture 2 Exercises¶

Write code to divide the integer value 3 by the integer value 7, and save the resulting value in the variable y. Then write code to divide the floating point value 3.0 by the integer value 7, and save the resulting value in the variable b. (Consider, before you write the code or print out the values: what type of value will be stored in the variable y? What type of value will be stored in the variable b?) ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(y, 0, "Testing the value of the variable y.") self.assertEqual(b, 3.0/7, "Testing the value of the variable b.") myTests().main()

Write code to let the user input their name. Store the string in a variable. Then write code to print out Welcome to the world of programming, <USER'S NAME> (except instead of “<USER’S NAME>” should be the name the user typed). # Write your code here. ===== print "\n We can't test code that requires user input in this case.\n"

Below is some code that assigns values to variables. Write code below it that makes it so that the variable x holds an integer value that is greater by 2 than the integer value it currently holds. That code should work no matter what the current value of x is! Then, write code that makes the variable apple hold the string value "television". Do not change any of the existing code. y = 5 apple = 7 x = 3 pasta = "delicious" ===== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(x,5,"Testing value of x.") self.assertEqual(apple,"television", "Testing value of apple.") self.assertNotIn("x = 5", self.getEditorText(), "Testing to make sure there is no hard-coding to reassign the variable x. (Don't worry about actual and expected values.)") myTests().main()
