python子类如何重用父类功能

class people:
    def __init__(self,name,age,sex):
        self.name=name
        self.age=age
        self.sex=sex
 
 
 
 
class boss(people):
    def __init__(self,name,age,sex,level,salary):
     #下面两行代码效果一样
        super(boss,self).__init__(name,age,sex)
        super().__init__(name,age,sex)
 
        self.level = level
        self.salary=salary
 
print(boss.mro())
print('='*50)
tea_obj=boss('资本家',18,'不限',10,9000)
print(tea_obj.__dict__)
