RE: Class Takes No Arguments - Larz60+ - Mar-30-2020 code has changed, error line number doesn't match code. Please post code with corresponding error trace. RE: Class Takes No Arguments - buran - Mar-30-2020 You have typo on this lines: def __int__(self, make, model, year): """Initialize attributes of the parent class.""" super().__int__(make, model, year)it should be def __init__(self, make, model, year): """Initialize attributes of the parent class.""" super().__init__(make, model, year)also in Car class: def __int__(self, make, model, year):should be def __init__(self, make, model, year): RE: Class Takes No Arguments - horuscope42 - Mar-30-2020 class Car: """A simple attempt to represent a car.""" def __int__(self, make, model, year): """Initialize the car.""" self.make = make self.model = model self.year = year self.odometer_reading = 0 def get_descriptive_name(self): """Return a description of the car in a neat format.""" long_name = f"{self.year} {self.make} {self.model}" return long_name.title() def read_odometer(self): """Creates a statement of the car mileage.""" print(f"This car has {self.odometer_reading} miles on it.") def update_odometer(self, mileage): """Create a method for updating the mileage of the odometer.""" if mileage >= self.odometer_reading: self.odometer_reading = mileage else: print(f"You can't roll back an odometer.") def increment_odometer(self, miles): """Defines the increment increase of the odometer.""" self.odometer_reading += miles """The '+=' symbology has been confusing but I tend to think of it as, ex) 'a += b'' is == to 'a = a + b'.

RE: Class Takes No Arguments - not_username1234 - Oct-26-2020 Dunno if this might still be of actuality for you but pay attention to the way you wrote the __init__ method. You wrote it __int__ instead of __int__ thus making your class unable to accept arguments |
