Python implementation class inheritance instance

Python is an interpreted, object-oriented, and dynamic data-type high-level programming language. This document describes an example of Python class inheritance.

The instance code is as follows:

#! /usr/bin/python # Filename: inherit.py # Author: yanggang class SchoolMember:   def __init__(self,name,age):     self.name = name     self.age = age     print 'init SchoolMember: ', self.name   def tell(self):     print 'name:%s; age:%s' % (self.name, self.age) class Teacher(SchoolMember):   def __init__(self,name,age,salary):     SchoolMember.__init__(self,name,age)     self.salary = salary     print 'init Teacher: ', self.name   def tell(self):     SchoolMember.tell(self)     print 'salary: ', self.salary class Student(SchoolMember):   def __init__(self,name,age,marks):     SchoolMember.__init__(self,name,age)     self.marks = marks     print 'init Student: ', self.name   def tell(self):     SchoolMember.tell(self)     print 'marks: ', self.marks t = Teacher('yanggang', 20, 1000) s = Student('liming', 12, 86) members = [t,s] print for member in members:   member.tell() 

Running result:
