1.隐藏对象的属性
class Dog:
def set_age(self,new_age):
if new_age>0 and new_age<=100:
self.age = new_age
else:
self.age = 0
def get_age(self):
return self.age
dog = Dog()
#dog.age = -10
#dog.name = "小白"
#print(dog.age)
dog.set_age(-10)
age = dog.get_age()
print(age)
#dog.get_name()
dog.age = -10
print(dog.age)
2.隐藏对象的属性,私有属性
class Dog:
def __init__(self, new_name):
self.name = new_name
self.__age = 0#定义了一个私有的属性,属性的名字是__age
def set_age(self,new_age):
if new_age>0 and new_age<=100:
self.__age = new_age
else:
self.__age = 0
def get_age(self):
return self.__age
dog = Dog("小白")
#dog.age = -10
#dog.name = "小白"
#print(dog.age)
dog.set_age(-10)
age = dog.get_age()
print(age)
#dog.get_name()
#dog.__age = -10
print(dog.__age)
