python-超继承

超继承，就是父类的，子类会要，同时也会有自己的方法属性

class MatchMethod:
    def __init__(self,a,b):
        self.a=a
        self.b=b
    def add(self):
        return self.a+self.b
    def sub(self):
        return self.a-self.b
class MatchMethod_1(MatchMethod):
    def divide(self):
        return self.a/self.b
    def add(self):#重写
        super(MatchMethod_1,self).add()#超继承
        print(‘我说子类的加法‘,self.a+self.b)
if __name__ == ‘__main__‘:
    MatchMethod_1(1,2).add()
