Is there a better way of coding this?

Here is a working version:

def makeprop(truename, funname):
     def fget(self):
         setattr(self, truename, getattr(self, funname)())
         return getattr(self, truename)
     return property(fget, None, None)

class X(object):
     i = makeprop('_i', 'Fi')

     def __init__(self, k):
         self.k = k

     def Fi(self):
         return self.k

x = X(11)
print x.i

Thanks for the help,
