Python中将方法转为属性式访问

1.使用装饰器装饰器管理类属性

class Person(object):def __init__(self):self.__age = 0@propertydef age(self):return [e-mail] age(self, new_age):self.__age = new_agep = Person()
print(p.age)p.age = 20 
print(p.age)

2. 使用property函数

class Person(object):def __init__(self):self.__age = 0def set_age(self, new_age):if new_age >= 150:print("Age is out of range")elif new_age < 0:print("Age should be greater than or equal to 0")self.__age = new_agedef get_age(self):return self.__ageage = property(get_age, set_age)p = Person()
print( p.age )p.age = 100
print( p.age )
