python-类的继承（学习）

代码里用到了
1.类的定义
2.子类继承父类
（1）如何重新定义子类的__init__()方法；

class BenzCar:
	brand='奔驰'
	@staticmethod #定义类的方法
	def pressHorn()
		print("嘟嘟~~")
	def __init__(self,color,engineSN):
		self.color=color
		self.engineSN=engineSN
	def change(self,newColor): #定义实例的方法
		self.color=newColor
# 子类的继承
class Benz2016(BenzCar):
	price = 580000
	def __init__(self,color,engineSN,weight):#父类的参数也需要传
		# 首先调用父类的初始化方法
		BenzCar.__init__(self,color,engineSN) 
		self.weight = weight
		self.oilweight = 0
	def filloil(self,oilAdded):
		self.oilweight +=oilAdded
		self.weight += oilAdded
#子类的子类的继承
class Benz2016_01(Benz2016):
	def __init__(self,color,engineSN,weight)
		Benz2016.__init__(self,color,engineSN,weight)

car2 = Benz2016('red','111',1500)
