Solve the following python programming problem given the following code:
def test_cancelConnectTCPTimeout(self) : 
    '
        L{ClientCreator.connectTCP} inserts a very short delayed call between
        the time the connection is established and the time the L{Deferred}
        returned from one of its connect methods actually fires.  If the
        L{Deferred} is cancelled in this interval, the established connection is
        closed, the timeout is cancelled, and the L{Deferred} fails with
        L{CancelledError}.
        ' 
    def connect(reactor, cc) : 
        d = cc.connectTCP ('example.com', 1234) 
        (host, port, factory, timeout, bindAddress) = reactor.tcpClients.pop () 
        protocol = factory.buildProtocol (None) 
        transport = StringTransport () 
        protocol.makeConnection (transport) 
        return d 
return self._cancelConnectTimeoutTest (self) 

    
    

    Fix the buggy line: return self._cancelConnectTimeoutTest (self)
