记录Python类与继承的一个错误

今天在学python的类与继承的时候遇到一个错误，原来是自己在ctrl+c  ctrl+v的时候漏了一个括号

class Car():
    def __init__(self,make,year,model):
        self.make=make
        self.model=model
        self.year=year
        self.odometer_reading=0
    def get_descriptive_name(self):
        long_name=str(self.year)+" "+self.make+" "+self.model
        return long_name.title()
    def read_odometer(self):
        print("This car has "+str(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")
    def increment_odometer(self,miles):
        self.odometer_reading+=miles
class ElectricCar(Car):
    def __init__(self,make,model,year):
        super.__init__(make,year,model)
my_tesla=ElectricCar('tesla','model s',2016)
print(my_tesla.get_descriptive_name())

运行时出现了以下的错误

super.__init__(make,year,model)

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

原来是22行的super()那里少了一个括号。
