要继承自 Car 类

1. from car import Car
   
2. 
   
3. 
   
4. class ElectricCar(Car):
   
5.     def __init__(self, brand, size):
   
6.         super().__init__(brand, size)
   
7.         self.battery = 100
   
8.         self.rm = 100
   
9. 
   
10.     def battery(self):
    
11.         print('The electric capacity of electric vehicles is: ' + self.battery)
    
12. 
    
13.     def rm(self):
    
14.         print('The estimated remaining mileage of electric vehicle is: ' + self.rm)
    
15. 
    
16.     def running(self, C):
    
17.         C = int(C)
    
18.         self.miles += C
    
19.         self.rm -= C
    
20.         self.battery -= (0.1) * C
    
21. 
    
22. 
    
23. my_new_car = ElectricCar('Tesla', 'Model S')
    
24. my_new_car.running(55)
    
25. my_new_car.rm()
    
26. my_new_car.battery()
