Summary
In this lab, you create a derived class from a base class, and then use the derived class in a Python program. The program should create two Motorcycle objects, and then set the Motorcycle’s speed, accelerate the Motorcycle object, and check its sidecar status.
Instructions
Open the file named Motorcycle.py.
Create the Motorcycle class by deriving it from the Vehicle class. Call the parent class __init()__ method inside the Motorcycle class's __init()__ method.
In theMotorcycle class, create an attribute named sidecar.
Write a public set method to set the value for sidecar.
Write a public get method to retrieve the value of sidecar.
Write a public accelerate method. This method overrides the accelerate method inherited from the Vehicle class. Change the message in the accelerate method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed: "This motorcycle cannot go that fast".
Open the file named MyMotorcycleClassProgram.py.

- A. Car Class Create a Python Program where you write a class named Car that has the following data attributes: • _ _year_model (for the car's year model) • __make (for the make of the car) • _ _speed (for the car's current speed) The Car class should have an _init_ method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the __speed data attribute. The class should also have the following methods: accelerate() The accelerate method should add 5 to the speed data attribute each time it is called. brake() The brake method should subtract 5 from the speed data attribute each time it is called. • get_speed() The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it.
