python @property和@attribute.setter理解

 

 

```python

class Human:

def init(self, name, age):
self.__name = name
self.__age = age

@property
def age(self):
return self.__age

@age.setter
def age(self, age):
if age > 0:
self.__age = age
else:
print('error')

h1 = Human('sai',22)
print(h1.age)
h1.age += 5
print(h1.age)
