python的继承

python继承过来的子类在初始化的时候不会自动调用父类的构造函数，得自己手动调用。 这里给一点简单的示例代码:


#! /usr/bin/python
# -*- coding:utf-8 -*-
# Filename : inherit.py

class Person:
    def __init__(self,name,age):
        self.name = name
        self.age = age
        print "init for %s" % self.name

    def tell(self):
        print "name:%s age:%d" % (self.name,self.age)

class Teacher(Person):
    def __init__(self,name,age,salary):
        Person.__init__(self,name,age)
        self.salary = salary
        print "init for teacher %s" % self.name

    def tell(self):
        Person.tell(self)
        print "salary:%d" % self.salary

p = Person('tianzhen',20)
p.tell()

tea_p = Teacher('zhenzhen',20,1010000000)
tea_p.tell()
