Question

1. Extending the answer from Python HW #7 for question #1, write the following python code to expand on the Car class. Include the python code you developed when answering HW #7.

1. Add class “getter” methods to return the values for model, color, and MPG

2. Add class “setter” methods to change the existing values for model, color, and MPG. The value to be used in the methods will be passed as an input argument.

3. Add class method that will calculate and return the number of miles driven, where the method is provided the size of the gas tank as an integer input

4. Below your Car class, create a new child class called mySportsCar that inherits from Car class. Make sure you call the Car class constructor with the appropriate inputs in the child class constructor.

5. Instantiate an object of the mySportsCar class. Use whatever appropriate input values that you would like.

HW#7:

class Car: condition = "new" def __init_(self, model, color, MPG): self.model = model self.color = color self.MPG = MPG my_car = Car("Corvette", "Black", 30) print("Model is:", my_car.model) print("Color is:", my_car.color) print("MPG is:", my_car.MPG)

Answer 1

Code

class Car:
condition="new"

def __init__(self,model,color,MPG):
self.model=model
self.color=color
self.MPG=MPG

#A. getter method
def getter(self):
return [ self.model , self.color , self.MPG ]
  
#B. setter method
def setter(self,model,color,MPG):
self.model=model
self.color=color
self.MPG=MPG

#C. Calculate No of Miles Driven
def miles(self,size):
return self.MPG/size

#D. Creating child class called mySportsCar
class mySportsCar( Car ):
def __init__(self , model , color , MPG , name):
self.name = name
Car.__init__(self, model , color , MPG )

  

my_car= Car("Corvette","Black",30)
print("Model is:",my_car.model)
print("Color is:",my_car.color)
print("MPG is:",my_car.MPG)

print(my_car.getter())
my_car.setter("Ford","Red",40)
print("Model is:",my_car.model)
print("Color is:",my_car.color)
print("MPG is:",my_car.MPG)

print("Miles Driven :",my_car.miles(40))

#E. Instantiate an object of the mySportsCar class
new_car = mySportsCar("Forge","Blue",50,"New")
print("Model is:",new_car.model)
print("Color is:",new_car.color)
print("MPG is:",new_car.MPG)
print("Name is:",new_car.name)

Output:

Model is: Corvette Color is: Black MPG is: 30 ['Corvette', 'Black', 30] Model is: Ford Color is: Red MPG is: 40 Miles Driven : 1.0 Model is: Forge Color is: Blue MPG is: 50 Name is: New
