Think for your remark " You didn't delete the name property, which is
part of the class, not the instance."
I fix my codes to get the target done.
class Person(object):
def addProperty(self, attribute):
getter = lambda self: self._getProperty(attribute)
setter = lambda self, value: self._setProperty(attribute,
value)
deletter = lambda self:self.delProperty(attribute)
setattr(self.__class__, attribute,
property(fget=getter,fset=setter,fdel=deletter,doc="Auto-generated method"))
def _setProperty(self, attribute, value):
setattr(self, '_' + attribute, value.title())
def _getProperty(self, attribute):
return getattr(self, '_' + attribute)
def delProperty(self,attribute):
delattr(self,'_' + attribute)
delattr(self.__class__, attribute)
I am so happy .

You deleted the _name attribute where you're storing the value of the
name property. You didn't delete the name property, which is part of
the class, not the instance.
