Python，获取 AttributeError: 'ElectricCar' 对象没有属性

Question

class Car:

    def __init__(self, year, make, model):

        self.year = year

        self.make = make

        self.model = model

        self.odometer_reading = 0

    def get_descriptive_name(self):

        long_name = str(self.year) + ' ' + str(self.make) + ' ' +str(self.model)

        return long_name.title()

    def read_odometer(self):

        print('This car has ' + str(self.odometer_reading) + ' miles on it')

    def update_odometer(self, mileage):

        self.odometer_reading = mileage

        if mileage >= self.odometer_reading:

            self.odometer_reading = mileage

        else:

            print('you cant roll it back')

class Battery():

    """A simple attempt to model a battery for an electric car."""

    def __init__(self, battery_size=70):

        self.battery_size = battery_size

    def describe_battery(self):

        " ""Print a statement describing the battery size."""

        print("This car has a " + str(self.battery_size) + "-kWh battery.")

#The call to the battery attribute in the ElectricCar class is where the         

#error emanates

class ElectricCar(Car):

    def __inti__(self, make, model, year):

        super().__init__(make, model, year)

        self.battery = Battery()

my_telsa = ElectricCar('Volvo', 'models s', 2006)

print(my_telsa.get_descriptive_name())

my_telsa.battery.describe_battery()

Answer 1

那么拼错错误，所以不是__inti__它__init__的ElectricCar课，所以是那么：...class ElectricCar(Car):    definit(self, make, model, year):        super().__init__(make, model, year)            self.battery = Battery()    ...

Answer 2

它_init_不在_inti_类 ElectricCar
