麻烦大佬看下为啥调用实例类密码函数无法用property

Question

class user:
def init(self,name='abcdefg',password='1234567'):
#双下划线开头，隐藏变量
self.__name=name
self.__password=password

def getname(self):
    return self.__name;
def setname(self,name):
    if isinstance(name,str) and 4<= len(name) <=8:
        self.__name = name
    else:
        print("无效用户名")
name=property(fget=getname,fset=setname);

@property
def getpwd(self):
    return self.__password;
@getpwd.setter
def setpwd(self,password):
    if isinstance(password,str) and 4 <= len(password) <= 8:
        self.__password = password
    else:
        print("无效密码")
# password = property(fget=getpwd, fset=setpwd);

c=user()
c.name='a'
c.password='1'

Answer 1

property 用错了
修改为我下面的这种

class user:
    def init(self, name='abcdefg', password='1234567'):
        # 双下划线开头，隐藏变量
        self.__name = name
        self.__password = password

    def getname(self):
        return self.__name

    def setname(self, name):
        if isinstance(name,str) and 4<= len(name) <= 8:
            self.__name = name
            print("用户名设置成功")
        else:
            print("无效用户名")

    name = property(fget=getname, fset=setname)

    @property
    def password(self):
        """I'm the 'password' property."""
        return self.__password

    @password.setter
    def password(self, password):
        if isinstance(password, str) and 4 <= len(password) <= 8:
            self.__password = password
            print("密码设置成功")
        else:
            print("无效密码")

c = user()
c.name = 'abcde'
c.password = '12345'
