Python 面向对象2

类的继承（Python支持多继承）

class Student(People):
    stu_number=0
    def __init__(self,name,sex,address,age,stu_number):
        self.name = name
        self._sex = sex
        self._People__adress = address
        super(Student,self).__init__(age)
        self.stu_number = stu_number

student = Student('张ng','男','的是非地方',26,100010)
print(dir(student))
print(student.name)
print(student._sex)
print(student._People__adress)
print(student._People__age)
print(student.stu_number)
student.walk
student._People__heihei()
print('student 是否是 People的实例：',isinstance(student,People))
print('student 是否是 Student的实例',isinstance(student,Student))
print('Student 是否是 People的子类',issubclass(Student,People))
