Before you keep reading...

Runestone Academy can only continue if we get support from individuals like you. As a student you are well aware of the high cost of textbooks. Our mission is to provide great books to you for free, but we ask that you consider a $10 donation, more if you can or less if $10 is a burden.

Before you keep reading...

Making great stuff takes time and $$. If you appreciate the book you are reading now and want to keep quality materials free for other students please consider a donation to Runestone Academy. We ask that you consider a $10 donation, but if you can give more thats great, if $10 is too much for your budget we would be happy with whatever you can afford as a show of support.

5.28. Functions and Conditionals Write Code Questions

1. Write a function called cropped_photo that takes the height and width of a photo. If the height and width are equal, then the function returns "Cropped Photo". Otherwise, it returns "The photo needs to be cropped." Assume height and width are positive. For example, cropped_photo(23.2, 23.2) should return "Cropped Photo".

   def cropped_photo(height, width): # write code here ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(cropped_photo(30, 80),"The photo needs to be cropped.","cropped_photo(30, 80)") self.assertEqual(cropped_photo(50, 50),"Cropped Photo","cropped_photo(50, 50)") self.assertEqual(cropped_photo(50.5, 50),"The photo needs to be cropped.","cropped_photo(50.5, 50)") self.assertEqual(cropped_photo(23.2, 23.2),"Cropped Photo","cropped_photo(23.2, 23.2)") myTests().main()

   Write a function called cropped_photo that takes the height and width of a photo. If the height and width are equal, then the function returns "Cropped Photo". Otherwise, it returns "The photo needs to be cropped." Assume height and width are positive. For example, cropped_photo(23.2, 23.2) should return "Cropped Photo".

   def cropped_photo(height, width): if height == width: return "Cropped Photo" else: return "The photo needs to be cropped."

2. Write a function called bonus that takes two parameters, years and quality. If years is more than 5, then the person gets a bonus. The person also gets a bonus if their quality of work was more than 90. They can also get a bonus if they worked for at least 3 years and had quality more than 80. If the person is eligible for a bonus, return "Eligible for Bonus". Otherwise, return "Ineligible for Bonus". For example, bonus(3, 81) should return "Eligible for Bonus".

   def bonus(years, quality): # write code here ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(bonus(7, 40),"Eligible for Bonus","bonus(7, 40)") self.assertEqual(bonus(5, 40),"Ineligible for Bonus","bonus(5, 40)") self.assertEqual(bonus(2, 98),"Eligible for Bonus","bonus(2, 98)") self.assertEqual(bonus(2, 90),"Ineligible for Bonus","bonus(2, 90)") self.assertEqual(bonus(3, 81),"Eligible for Bonus","bonus(3, 81)") self.assertEqual(bonus(4, 81),"Eligible for Bonus","bonus(4, 81)") self.assertEqual(bonus(3, 67),"Ineligible for Bonus","bonus(3, 67)") self.assertEqual(bonus(3, 80),"Ineligible for Bonus","bonus(3, 80)") self.assertEqual(bonus(2, 88),"Ineligible for Bonus","bonus(2, 88)") myTests().main()

3. Write a function called move_elevator that takes two parameters, current_floor and next_floor. If the elevator moves to a floor above, then it should return "Up". Otherwise, it should return "Down". Also, if next_floor is the same as current_floor, it should return 0. Assume there are no 0 or negative floors. For example, move_elevator(5, 8) should return "Up".

   def move_elevator(current_floor, next_floor): # write code here ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(move_elevator(5, 8),"Up","move_elevator(5, 8)") self.assertEqual(move_elevator(2, 2),0,"move_elevator(2, 2)") self.assertEqual(move_elevator(9, 3),"Down","move_elevator(9, 3)") myTests().main()

   Write a function called move_elevator that takes two parameters, current_floor and next_floor. If the elevator moves to a floor above, then it should return "Up". Otherwise, it should return "Down". Also, if next_floor is the same as current_floor, it should return 0. Assume there are no 0 or negative floors. For example, move_elevator(5, 8) should return "Up".

   def move_elevator(current_floor, next_floor): if next_floor < current_floor: return "Down" elif next_floor > current_floor: return "Up" else: return 0

4. Write a function called lunch_break that takes a parameter class_standing and determines how long a lunch break will be based on the student’s class standing. If a person is a ‘Freshman’, return 40. If a person is a ‘Sophomore’, return 30. If a person is a ‘Junior’, return 20. If a person is a ‘Senior’, return 15. If a person is none of these, return 0. For example, lunch_break('Alumni') should return 0.

   def lunch_break(class_standing): # write code here ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(lunch_break('Freshman'),40,"lunch_break('Freshman')") self.assertEqual(lunch_break('Sophomore'),30,"lunch_break('Sophomore')") self.assertEqual(lunch_break('Junior'),20,"lunch_break('Junior')") self.assertEqual(lunch_break('Senior'),15,"lunch_break('Senior')") self.assertEqual(lunch_break('Alumni'),0,"lunch_break('Alumni')") myTests().main()

5. Write a function called pay_rent that takes in one parameter, units. If units is less than 200, return "$100". If units is less than 500 and greater than or equal to 200, return "$200". Otherwise, return "$300". For example, pay_rent(175) should return "$100".

   def pay_rent(units): # write code here ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(pay_rent(175), "$100","pay_rent(175)") self.assertEqual(pay_rent(199), "$100","pay_rent(199)") self.assertEqual(pay_rent(200), "$200","pay_rent(200)") self.assertEqual(pay_rent(201), "$200","pay_rent(201)") self.assertEqual(pay_rent(373), "$200","pay_rent(373)") self.assertEqual(pay_rent(499), "$200","pay_rent(499)") self.assertEqual(pay_rent(500), "$300","pay_rent(500)") self.assertEqual(pay_rent(501), "$300","pay_rent(501)") self.assertEqual(pay_rent(1007), "$300","pay_rent(1007)") myTests().main()

   Write a function called pay_rent that takes in one parameter, units. If units is less than 200, return "$100". If units is less than 500 and greater than or equal to 200, return "$200". Otherwise, return "$300". For example, pay_rent(175) should return "$100".

   def pay_rent(units): if units < 200: return "$100" elif units < 500: return "$200" else: return "$300"

6. Write a function called play_weather that takes the string weather as a parameter and returns if one should play or not. If the weather is ‘sunny’ or ‘cloudy’, then the function should return "The person should play". If the weather is ‘rainy’, ‘windy’ or ‘snowy’, then the function should return "The person should not play". If the weather is none of these, the function should return "It is not safe to go outside". For example, play_weather('sunny') should return "The person should play".

   def play_weather(weather): # write code here ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(play_weather('sunny'), "The person should play", "play_weather('sunny')") self.assertEqual(play_weather('cloudy'), "The person should play", "play_weather('cloudy')") self.assertEqual(play_weather('rainy'), "The person should not play", "play_weather('rainy')") self.assertEqual(play_weather('windy'), "The person should not play", "play_weather('windy')") self.assertEqual(play_weather('snowy'), "The person should not play", "play_weather('snowy')") self.assertEqual(play_weather('stormy'), "It is not safe to go outside", "play_weather('stormy')") myTests().main()
