python property的2种使用方法

一、property类

 class Person():
     def __init__(self, name):
         self.set_name(name)

     def get_name(self):
         return self.__name

     def set_name(self, name):
         self.__name = name

     name = property(get_name, set_name)

 p = Person('xiaoliu')
 print(p.name)
 p.name = 'banana'
 print(p.name)

二、property修饰器

 class Person():
     def __init__(self, name):
         self.name = name

     @property
     def name(self):
         return self.__name

     @name.setter
     def name(self, name):
         self.__name = name

 p = Person('xiaoliu')
 print(p.name)
 p.name = 'banana'
 print(p.name)
