python使用 __init__初始化操作简单示例

本文实例讲述了python使用 __init__初始化操作。分享给大家供大家参考，具体如下：

# -*- coding:utf-8 -*-
# !/usr/bin/python
class Dog():
 """"一次模拟小狗的简单尝试"""
 def __init__(self,name,age):
 """初始化属性name和age"""
 print self
 print type(self)
 print dir(self)
 self.name = name
 self.age = age
 def sit(self):
 """模拟小狗被命令时蹲下"""
 print self.name.title() + "is now sitting."
 def roll_over(self):
 """模拟小狗被命令时打滚"""
 print (self.name.title() + "rolled over!")
a=Dog('aaaa','bbbb')

运行结果：

C:\Python27\python.exe C:/Users/TLCB/PycharmProjects/untitled2/object/dog.py <__main__.Dog instance at 0x020F2BC0> <type 'instance'> ['__doc__', '__init__', '__module__', 'roll_over', 'sit']
