Instructions#

Write a class named Rocket that has attributes named name, booster_cost, upper_stage_cost, and fuel_cost, and has a method named cost_per_launch. All of the class’s attributes should be set during instantiation. The cost_per_launch method should calculate the cost of a launch as the sum of the booster_cost, the upper_stage_cost, and the fuel_cost, and then print out the cost to launch the rocket.

Next, write a ReusableRocket class that inherits from Rocket. This class should have all the same attributes as Rocket plus an attribute named uses that represents the number of times the rocket’s booster stage can be used. The ReusableRocket class should override the inherited cost_per_launch method such that it calculates the launch cost as the booster_cost divided by uses, plus the upper_stage_cost, plus the fuel_cost.

In the main function of your program, create the five rockets listed in Table 11.4. The first four rockets should be instances of Rocket, but the fifth one should be an instance of ReusableRocket. Then call the cost_per_launch method on each of them.

Sample Output#

Ensure your program’s output matches the provided samples exactly. This includes all characters, white space, and punctuation. In the samples, user input is highlighted like this for clarity, but your program should not highlight user input in this way.

Deliverables#

Save your finished program as rockets_login.py, replacing login with your Purdue login. Then submit it along with all the deliverables listed in Table 11.5 below.
