Solve the following python programming problem given the following code:
@ tornado.gen.coroutine 
def send_id(self, tok, force_auth) : 
    '
        Send the minion id to the master so that the master may better
        track the connection state of the minion.
        In case of authentication errors, try to renegotiate authentication
        and retry the method.
        ' 
    load = { 
        'id' : _do_transfer.opts ['id'], 
        'tok' : tok, 
} 
    @ tornado.gen.coroutine 
    def _do_transfer() : 
        msg = self._package_load (self.auth.crypticle.dumps (load)) 
        package = salt.transport.frame.frame_msg (msg, header = None) 
        (yield self.message_client._stream.write (package)) 
        raise tornado.gen.Return (True) 
if (force_auth or (not self.auth.authenticated)) : 
        (yield self.auth.authenticate ()) 
try : 
        ret = (yield _do_transfer ()) 
        raise tornado.gen.Return (ret) 
except salt.crypt.AuthenticationError : 
        (yield self.auth.authenticate ()) 
        ret = (yield _do_transfer ()) 
        raise tornado.gen.Return (ret)
