9/11. Inheritance


What did I do in a wrong way? Thank you in advance.


Oops, try again. You should define init() for both Car and ElectricCar.
Traceback (most recent call last):
File "python", line 23, in
TypeError: init() takes exactly 4 arguments (5 given)

Next task.

class Car(object):
    condition = "new"
    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg
    def display_car(self):
        return "This is a %s %s with %s MPG." % (self.color, self.model, self.mpg)
    def drive_car(self):
        self.condition = "used"

my_car = Car("DeLorean", "silver", 88)
print my_car.condition

class ElectricCar(Car):
    def __int__(self, model, color, mpg, battery_type):
        self.model = model
        self.color = color
        self.mpg   = mpg   
        self.battery_type = battery_type
my_car = ElectricCar("DeLorean", "silver", 88, "molten salt")
print my_car.condition

print my_car.condition


in ElectricCar you misspelled init


Ohhh how I could be so stupid. Thank you very much.
