python中property装饰器

property装饰器，用来将一个get方法，转换为对象的属性，添加为property装饰器以后，我们就可以向调用属性一样使用get方法。往往和setter方法装饰器一起使用。

class Person :
    def __init__(self,name='',age=20, sex='man'):
        self.__name = name      # 私有属性
        self.__age = age
        self.__sex = sex
    @property  # property装饰器，用来将一个get方法，转换为对象的属性，添加为property装饰器以后，我们就可以向调用属性一样使用get方法
    def name(self):
        return self.__name
    @name.setter # setter方法装饰器：@属性名.setter
    def name(self,name):
        self.__name = name
    def setName(self,name):
        if not isinstance(name,str) :
            print('name must be string')
            return
        self.__name = name

    @property
    def age(self):
        return self.__age
    @age.setter
    def age(self, age):
        self.__age = age
    def setAge(self,age):
        if not isinstance(age,int) :
            print('age must be int')
            return
        self.__age = age

    @property
    def sex(self):
        return self.__sex
    @sex.setter
    def sex(self, sex):
        self.__sex = sex

    def setSex(self,sex):
        if sex != 'man' and sex != 'woman' :
            print('sex must be "man" or "woman"')
            return
        self.__sex = sex

    def show(self):
        print('Name:',self.__name)
        print('Age:',self.__age)
        print('Sex:',self.__sex)

p = Person('小明','18','man')
p.show()
