Python学习笔记——Property用法

写法一

class Test(object):
"""docstring for Test"""
def __init__(self):
super(Test, self).__init__()
self.__num = 10

def getNum(self):
return self.__num

def setNum(self,newNum):
self.__num = newNum

num = property(getNum,setNum)

写法二（装饰器）

class Test(object):
"""docstring for Test"""
def __init__(self):
super(Test, self).__init__()
self.__num = 100

@property
def num(self):
return self.__num

@num.setter
def num(self,newNum):
self.__num = newNum
