今天在學python的類與繼承的時候遇到一個錯誤，原來是自己在ctrl+c  ctrl+v的時候漏了一個括號

 1 class Car():
 2     def __init__(self,make,year,model):
 3         self.make=make
 4         self.model=model
 5         self.year=year
 6         self.odometer_reading=0
 7     def get_descriptive_name(self):
 8         long_name=str(self.year)+"
 
 "+self.make+" "+self.model
 9         return long_name.title()
10     def read_odometer(self):
11         print("This car has "+str(self.odometer_reading)+"miles on it")
12 
13     def update_odometer(self,mileage):
14         if mileage>=self.odometer_reading:
15             self.odometer_reading=mileage
 
16         else:
17             print("You can't roll back an odometer")
18     def increment_odometer(self,miles):
19         self.odometer_reading+=miles
20 class ElectricCar(Car):
21     def __init__(self,make,model,year):
22         super.__init__(make,year,model)
23 my_tesla=ElectricCar('tesla','
 
model s',2016)
24 print(my_tesla.get_descriptive_name())

執行時出現了以下的錯誤

super.__init__(make,year,model)

TypeError: descriptor '__init__' requires a 'super' object but received a 'str'

原來是22行的super()那裡少了一個括號。
