Python类继承的实现

代码：

#! /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()

结果：

[work@db-testing-com06-vm3.db01.baidu.com python]$ python inherit.py

init SchoolMember:  yanggang

init Teacher:  yanggang

init SchoolMember:  liming

init Student:  liming

name:yanggang; age:20

salary:  1000

name:liming; age:12

marks:  86
