Question

python
Design a class named Car that has the following fields:

yearModel: The yearModel field is an Integer that holds the car’s year model.

make: The make field references a String that holds the make of the car.

speed: The speed field is an Integer that holds the car’s current speed.

In addition, the class should have the following constructor and other methods:

Constructor: The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.

Accessors: Design appropriate accessor methods to get the values stored in an object’s yearModel, make, and speed fields.

accelerate: The accelerate method should add 5 to the speed field each time it is called.

brake: The brake method should subtract 5 from the speed field each time it is called.

Next, design a program that creates a Car object, and then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method five times. After each call to the brake method, get the current speed of the car and display it.

Answer 1

Points to consider:

1. We need to create the Car Class.
2. Then we need to make the object out of it.
3. Then we need to print the speed each time we accelerate and then brake for five times and display speed each time.

Code

class Car:
    def __init__(self, year_model, make):
        self.year_model = year_model
        self.make = make
        self.speed = 0

    def getYearModel(self):
        return self.year_model

    def setYearModel(self, year_model):
        self.year_model = year_model

    def getMake(self):
        return self.make

    def setMake(self, make):
        self.make = make

    def getSpeed(self):
        return self.speed

    def setSpeed(self, speed):
        self.speed = speed

    def accelerate(self):
        self.speed += 5

    def brake(self):
        if self.speed >= 5:
            self.speed -= 5
        else:
            self.speed = 0


def main():
    c = Car(2015, "Honda")
    for i in range(5):
        c.accelerate()
        print("Speed: ", c.getSpeed())

    for i in range(5):
        c.brake()
        print("Speed: ", c.getSpeed())

main()
