    def __init__(self, manufacturer, model, hp):
        self.manufacturer = manufacturer
        self.model = model
        self.hp = hp

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()

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))
