如何从子类调用基类的__init__方法？

你可以用

super(ChildClass, self).__init__()

class baseClass(object):    def __init__(self, *args, **kwargs):        passclass ChildClass(baseClass):    def __init__(self, *args, **kwargs):        super(ChildClass, self).__init__(*args, **kwargs)

您的缩进不正确，这是修改后的代码：

class Car(object):    condition = "new"    def __init__(self, model, color, mpg):        self.model = model        self.color = color        self.mpg   = mpgclass ElectricCar(Car):    def __init__(self, battery_type, model, color, mpg):        self.battery_type=battery_type        super(ElectricCar, self).__init__(model, color, mpg)car = ElectricCar('battery', 'ford', 'golden', 10)print car.__dict__

这是输出：

{'color': 'golden', 'mpg': 10, 'model': 'ford', 'battery_type': 'battery'}
