class Student(object):
@property
def testname(self):
return self.name
@testname.setter
def testname(self,name):
self.name = name

s.testname = "alex"
print(s.testname)
alex
看上去的确好用，但其实python内置的__getattr__和__setattr__就是将方法变为属性功能的。
In [4]:
class Stu(object):
def __init__(self):
pass
def __setattr__(self,name,value):
self.__dict__[name] = value
def __getattr__(self):
return self.name
In [5]:
s = Stu()
s.name = 'alex'
print(s.name)
alex
结果当然是：alex 。
