    As mentioned you define a name for an increment_odometer object in the __init__ and later define a method with the same name. Just remove the self.increment_odometer = 0 in the __init__

    class Car():
    
        def __init__(self, make, model, year):
            """initialize attribuites to describe a car"""
            self.make = make
            self.model = model
            self.year = year
            self.odometer_reading = 0
            # self.increment_odometer = 0 ----> remove this line
    
        def update_odometer(self, mileage):
            """
            Set the odometer reading to the given value.
            Reject the change if it attempts to roll the odometer back.
            """
            if mileage >= self.odometer_reading:
                self.odometer_reading = mileage
            else:
                print("You cannot roll back the odometer.")
    
        def read_odometer(self):
            """print at statement which shows the car's miles"""
            print("This car has " + str(self.odometer_reading) + " " + "miles on it.")
    
        def get_descriptive_name(self):
            """Return a neatly formatted descriptive name."""
            long_name = str(self.year) + ' ' + self.make + ' ' + self.model
            return long_name.title()
    
        def increment_odometer(self, miles):
            """Add the given amount to the odometer reading."""
            self.odometer_reading += miles
    
    
    my_old_car = Car ('subaru', 'outback', 2013)
    print (my_old_car.get_descriptive_name())
    
    my_old_car.update_odometer(23500)
    my_old_car.read_odometer()
    
    my_old_car.increment_odometer(100)
    my_old_car.read_odometer()
