不多说，直接上代码：

import time
    class Car():
    
        def __init__(self,make,model,year):
            self.make = make
            self.model =model
            self.year = year
            self.odometer_read = 230#指定一个默认属性值
    
        def describe(self):
            message = str(self.year)+' '+self.make.upper()+' '+self.model
            return message
    
        # def read_odometer(self):
        #     print('The car has '+str(self.odometer_read)+' miles on it.')
    
        def updata_odometer(self,mileage):#通过定义一个方法来修改默认值
            if mileage >self.odometer_read:
                self.odometer_read = mileage#通过定义一个范围，来禁止回调
            else:
                print('You can not roll back an odometer!')
    
        def increment_odometer(self,mileage):
            active = True
            start = time.time()
            while active:
                localtime = time.asctime(time.localtime(time.time()))
                time.sleep(1)
                print(localtime)
                self.odometer_read += mileage
                print('The car has ' + str(self.odometer_read) + ' miles on it.')
                if self.odometer_read == 10000:
                    active = False
                    print('!!!!!!!!!!!!!!!!!!!')
                     end = time.time()
                    ex_time = end - start
                    print('The expend time is '+str(ex_time)+' .')
    
    car = Car('bmw','X6',2018)
    print(car.describe())
    car.updata_odometer(1000)
    car.increment_odometer(100)
    # car.read_odometer()
