Need help in finding the error

• swiss_knight: You have no such print_info method defined in your class.

Answer 1

As it is stated in the error message, tou have no method by the name print_info. Probably, you're trying to do:

myCar1.print_car_amount()

Answer 2

class Car:
amount_cars = 0
def __init__(self, manufacturer, model, hp):
 self.manufacturer = manufacturer
 self.model = model
 self.hp = hp
 Car.amount_cars += 1
def print_info(self): # Changed
 print("Amount: {}".format(Car.amount_cars))
