python ―类的继承

root@kali:~/python/mod# vi class2.pyroot@kali:~/python/mod# cat class2.py#!/usr/bin/python# --*-- coding:utf-8 --*--class person:  def __init__(self,name,nationality,age,sex,job):    self.Name = name    self.Country = nationality    self.Age = age    self.Sex= sex    self.Job = job  def talk(self,msg):    self.msg = msg#定义msg变量，可以在python交换环境中调用    if self.msg != 0:      print '''Hello %s,    you are from %s    you are %s years old    you are %s    your job is %s.    Am i right?''' %(self.Name,self.Country,self.Age,self.Sex,self.Job)  def skill(self):    if self.Job == 'IT Engineor':      print '''To be IT Engineor,you must many skills:\n    1.Linux    2.shell    3.database    4.python    '''  def action(self):    if self.msg != 2:      print 'call this fuction!!'    else:      passclass love(person):#继承父类peson信息，写恋爱史  def __init__(self,number_of_friends,name,nationality,age,sex,job):    person.__init__(self,name,nationality,age,sex,job)#继承父类信息    self.number = number_of_friends  def interaction(self):    first_lover = raw_input("please input your first love's name:")    first_age = raw_input("how oid are you?")    status = raw_input("what is your current status:?")    self.status = status    self.talk(2)    year_gap = int(self.Age) - int(first_age)    print '''\nAnd your personal relationships as folloe:    your met your first when you were %s,her name is %s    now you are %s,but %s years later,now xx years past ,you still in love with her!you have % friends'''% (first_age,first_lover,status,year_gap,self.number)#p = person('xuweibo','CN','19','Malse','IT Engineor')p2 = love(2,'xuweibo','CN','76','Malse','IT Engineor')p2.interaction()'''#--------绑定实例-------------p = person('xuweibo','CN','19','Malse','IT Engineor')p.talk(1)p.skill()p.action()#----------------------------#----------不绑定实例-------------------#person('xuweibo','CN','19','Malse','IT Engineor').talk(2)#person('xuweibo','CN','19','Malse','IT Engineor').skill()#--------------------------------------'''root@kali:~/python/mod#

运行：

root@kali:~/python/mod#root@kali:~/python/mod# python class2.pyplease input your first love's name:cuihuahow oid are you?21what is your current status:?sigleHello xuweibo,    you are from CN    you are 76 years old    you are Malse    your job is IT Engineor.    Am i right?And your personal relationships as folloe:    your met your first when you were 21,her name is cuihua    now you are sigle,but 55 years later,now xx years past ,you still in love with her!you have 2.000000riendsroot@kali:~/python/mod#
