但是，如果改成私有属性，就全部报错了~~~

按照你的例子编写的程序，为啥，是这样显示的呢？（代码都一样，所以有些地方就不复制了）

class Sample(Total, Student, People): def init(self, name, age, grade, like, say): Total.init(self, name, say) Student.init(self, name, age, grade, like)

a = Sample("Jack", 12, 5, "Python", "JAVA+Python") a.print_date()

为啥执行的结果是这样的呢？？ My name is Jack,12 years old in 5 grade,I like Python

我已经把People的父类继承给了Student 最后的Sample，因为Student已经继承了People 所以class Sample就不用加People，直接

class Sample（Total，Student）：

然后，你把Tolat 和 Student的位置互换一下

Class Sample（Student，Total）：

再执行一下结果如果要把People加上Sample的话，Student就不要继承People了~~

方法名同，默认调用的是在括号中排前地父类的方法
