python property的2种使用方法

一、property类

 1 class Person():
 2     def __init__(self, name):
 3         self.set_name(name)
 4 
 5     def get_name(self):
 6         return self.__name
 7 
 8     def set_name(self, name):
 9         self.__name = name
10 
11     name = property(get_name, set_name)
12 
13 p = Person('xiaoliu')
14 print(p.name)
15 p.name = 'banana'
16 print(p.name)

二、property修饰器

 1 class Person():
 2     def __init__(self, name):
 3         self.name = name
 4 
 5     @property
 6     def name(self):
 7         return self.__name
 8 
 9     @name.setter
10     def name(self, name):
11         self.__name = name
12 
13 p = Person('xiaoliu')
14 print(p.name)
15 p.name = 'banana'
16 print(p.name)
