我的朋友們，我檢查我的語法代碼是正確的，同志們，謝謝你的幫助
我的代碼：
class person:
def __init__(self,name,family):
self.name = name
self.family = family
@property
def fullname(self):
return f"{self.name} {self.family}"
class user(person):
def __init__(self,name,family,age):
super().__init__(name,family)
self.age = age
@property
def age(self):
return self.age
@age.setter
def age(self,age_new):
self.age = age_new
emanuel = user("emanuel","victor",15)
print(emanuel.fullname)
print(emanuel.age)
emanuel.age = 20
print(emanuel.age)
錯誤：同志們，我正在訓練，我得到了很多錯誤，但是我真的能做些什么呢？

uj5u.com熱心網友回復：
您需要使用與您的屬性不同名稱的屬性。否則，當您嘗試self.age從 setter 方法內部進行設定時，setter 會呼叫自身。
試試這個：
class User(Person):
def __init__(self, name, family,age):
super().__init__(name, family)
self._age = age
@property
def age(self):
return self._age
@age.setter
def age(self, age_new):
self._age = age_new
