Question

Create a car class with three attributes: year, mpg, speed and list of owners. The class also should have 2 methods called accelerate and brake. Whenever the car accelerates, its speed is increased by 30 and whenever the car brakes, its speed is reduced by 60.

1. add a constructor to the class, which takes year, mpg, and speed as input
2. implement a magic method that prints the car information including year, speed and mpg. That is, for a car object, car1=car(2016, 20, 80), print(car) command should print car_year_2016_mpg_20_speed_80.
3. create two car objects: car1 and car2. record 'John Doe' and 'Jack Jones' as the previous owners of car1 and 'John Flack' and 'Jeff Heath' as the previous owners of car2. Verify that the list of car1 owners and list of car2 owners are different.

Program code to copy:

class car:
def __init__(self,y,m,s):#constructor of class
self.year=y
self.mpg=m
self.speed=s
self.owner=[]
def accelerate(self):#increases speed by 30
self.speed+=30
def brake(self):#decreases speed by 60
self.speed-=60
def __str__(self):
return "car_year_"+str(self.year)+"_mpg_"+str(self.mpg)+"_speed_"+str(self.speed)

car1=car(2016,20,80)#create car objects
car2=car(2017,30,80)
car1.owner.append("John Doe")
car1.owner.append("Jack Jones")
car2.owner.append("John Flack")#add owners to cars
car2.owner.append("Jeff Heath")
print("car1 owners are :",car1.owner)
print("car2 owners are :",car2.owner)
if car1.owner==car2.owner:#check if the owners are same
print("The owners are same")
else:
print("The owners are different")
