Python 类的多重继承

类的多重继承

什么是多重继承

• 可以继承多个基(父)类

多重继承的方法

• class Child(Parent1, Parent2, Parent3...)

• 将被继承的类放入子类的参数位中,用逗号隔开

• 从左向右依次继承

代码

	# coding:utf-8
	# 1 2个父类
	class Tool(object):
	def work(self):
	return 'tool work'
	def car(self):
	return 'car will run'
	class Food(object):
	def work(self):
	return 'food work'
	def cake(self):
	return 'i like cake'
	# 继承父类的子类
	class Person(Food, Tool): # 最左边的类先被继承,如果有多个类,则最开始的那个类发生作用
	pass
	if __name__ == '__main__':
	p = Person()
	p_car = p.car()
	p_cake = p.cake()
	print(p_car)
	print(p_cake)
	p_work = p.work()
	print(p_work)
	print(Person.__mro__)
