python2里面的经典类的继承是深度优先
python2里面的新式类的继承是广度优先
python3里面的经典类和新式类的继承是广度优先
Python 2.x中默认都是经典类,只有显式继承了object才是新式类
Python 3.x中默认都是新式类,不必显式的继承object
class Teacher(SchoolMember,Person): def __init__(self,name,age,sex,salary,course): #SchoolMember.__init__(self,name,age,sex) #Person.__init__(self,dress) #不推荐以上继承方式,手动改变了python继承的顺序,会产生BUG super(Teacher,self).__init__(name,age,sex) self.salary = salary self.course = course
