## 概述 property可寫與可讀 ```python #!/usr/bin/env python class Test1: def __init__(self): self.__private = 'alex' @property def show(self): return self.__private ``` 類test1沒有繼承object，特性show在類外部可讀，可寫 ``` t1 = Test1() print t1.show t1.Show = 'change 1' print t1.show ``` ```python class Test2(object): def __init__(self): self.__private = 'alex' @property def Show(self): return self.__private @Show.setter def Show(self, value): self.__private = value ``` 類test2繼承object，特性show在類外部可讀，默認不可寫，需要通過設置setter變為可寫 ```python t2 = Test2() print t2.show t2.show = 'change 2' print t2.show ```
