Python类的继承用法示例

本文实例讲述了python类的继承用法。分享给大家供大家参考，具体如下：

python —类的继承

root@kali:~/python/mod# vi class2.py
root@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:
      pass
class 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').skill()
#--------------------------------------
'''
root@kali:~/python/mod#

运行：

root@kali:~/python/mod#
root@kali:~/python/mod# python class2.py
please input your first love's name:cuihua
how oid are you?21
what is your current status:?sigle
