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() takes at least 1 argument (0 given)

super() 函数有什么问题？

Answer 1

super()(无参数)在 python3 中引入 这是 python2 实现。

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

你可以引用this question关于 python2 和 python3
