在python里面运用多继承方法详解

1、在pyth里面运用多继承方法详解如何在里面运用多继承thhoy(self):pntotopyoothoopntotooonythn比如说有两个类，如果想要一个子类同时继承这两个类，应该怎么操作呢。pthobbint(yoothooprinttoplayooto00nythinonthothpononon.hobbyon.cook只要在子类名称的后面加入两个父类，就可以进行多继承了。Ind:classFalhei;Lefhobby(self):nrmtCloveioplayvideosane.)classMDihei:defcook(self):(xloveioccokanythin

10、nit_(sex)#要想调用特定父类的构造器只能使用父类名._init_方式。如下：Human._init_(self,sex)Person._init_(self,name)self.grade=gradeclassSon(Human,Teacher):def_init_(self,sex,name,age,fan):Human._init_(self,sex)Teacher._init_(self,name,age)self.fan=fan#创建对象stu=Student(tom,male,88)print(,stu.sex,stu.grade)stu.p()#虽然父类Human和Person都有同名P()方法，但是调用的是括号里的第一个父类Human的方法son1=So
