Is there a better way of coding this?

Yes.  Use getattr, setattr and a nested function.  Something like
this:

# very much untested code follows:
def makeprop(getname, truename, funnanme):
    def fget(self):
        # Subtle error processing here.
        setattr(self, truename, getattr(self, funname)(self.data))
        return getattr(self, truename)
    return property(fget, None, None)

class X(object):
    i = makeprop('geti', '_i', 'Fgeti')
    ...
