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 = f"{self.year} {self.make} {self.model}"
      return long_name.title()
def read_odometer(self):
      print(f"This car has {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!")

my_new_car = Car('audi','a4','2019')
print(my_new_car.get_descriptive_name())
my_new_car.update_odometer(23)
my_new_car.read_odometer()

class Battery:
def __init__(self,battery_size = 75):
      self.battery_size = battery_size

def describe_battery(self):
      print(f"This car has a {self.battery_size}-kwh battery.")


class ElectricCar(Car):
def __init__(self,make,model,year):
      super().__init__(make,model,year)
      self.battery = Battery()

my_tesla = ElectricCar('tesla','models','2019')
print(my_tesla.get_descriptive_name())
my_tesla.battery.describe_battery()

代码运行正常子类跟父类一起打印出来的
我想问怎么只要子类父类不要打出来
