Probably not necessary to start each title with "help" (which is pretty much implicit in the fact that there's a question asked on the list) or "beginner" (which isn't particularly helpful to us, as it could mean antyhing). Just a note for the future. :-)

I followed it step py step: [... useful stuff snipped ...] Like Michael, I can't see anything immediately wrong, but there are a lot of "next steps" you can take from here. Debugging is science. Reduce the number of variables in the experiment, make and take notes at every step (i.e. logging), etc. In this case, you have a template tag function that is hopefully being called. So verify that. Put a debugging print in as the very first line and see if it appears. If you're using the development server, the output of "print" will appear in the terminal where you started the dev server. If you're using a proper webserver, print to sys.stderr and the output will appear in the server's error logs. If the function is called, introduce a few more debugging prints to see what's happening along the way. Both in the template tag's function and in the render() method of the Node subclass you created, since that should eventually be called, too. You might also want to take this chance to investigate using pdb to investigate problems in Python. Search around a bit -- from memory, a lot of people have blogged about using pdb to debug Django and there have been posts on this list the past. Somebody -- and my memory is either Eric Florenzano or Eric Holscher -- even did a screencast on the topic, from memory. I don't personally debug things that way, so I can't offer more advice than that, but it floats some people's boat.
