贴一下调试过程自己犯的错误，警示自己，还是不够熟练

class Car():
    def __init__(self,make,model,year):
        self.make = make
        self.model = model
        self.year = year
        self.odometer_reading = 0

    def get_descriptive_name(self):
        long_name = str(self.year) + " " + self.make + " "\
                     + self.model
        print(long_name.title())

    def read_odometer(self):
        print("This car has " + str(self.odometer_reading)\
               + "miles on it.")

    def update_odometer(self,mileage):
        if mileage >= self.odometer_reading:
            self.odometer_reading = mileage
        else:
            print("You can't roll back an odometer!")

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

    def get_range(self):
        if self.battery_size == 70:
