场景：输入汽车品牌，再输入租借天数，输出总费用 父类
class car_base:
def __init__(self):
self.name = None
self.price = None
pass
def set_price(self):
pass
def get_total_price(self, day):
return self.price * int(day)
继承类
重写 init 方法，
class aodi(car_base):
def __init__(self):
self.name = '奥迪'
def set_price(self, price):
self.price = price
class jili(car_base):
def __init__(self):

def set_price(self, price):
self.price = price
class hongqi(car_base):
def __init__(self):
self.name = '红旗'
def set_price(self, price):
self.price = price
调用
if __name__ == '__main__':
