python super()函数错误？

Question

class car(object):

    def __init__(self, make, model, year):
        self.make = make
        self.model = model
        self.year = year
        self.odometer_reading = 0

class electricCar(car):
    def __init__(self, make, model, year):
        super().__init__(make, model, year)

tesla = electricCar('tesla', 'model s', 2016)
print tesla.get_descriptive_name()

TypeError:super()至少需要1个参数(给定0)

super()函数有什么问题？

Answer 1

super()(没有参数)是在python3中引入的. 这是 python2实现.

class electricCar(car):
    def __init__(self, make, model, year):
        super(electricCar,self).__init__(make, model, year)
