There is a saying amongst growers of bonsai trees: A tree isn't "finished" until it is dead. In other words, it keeps growing and so you constantly have to keep working on it. You can't just think of a design, prune the tree and then say, "Oh, I'm done! Let it stay like this forever". Software is exactly the same. Your needs may never changes, but the world around you does. You have no control of that and so you must constantly maintain your code -- even if there are no changes that you want. It's not just Python or django. It's hasn't even possible to compile Ruby 1.8.7 with recent versions of GCC for at least a year (don't ask me how I know... :-P ). Starting a software project -- any project -- is a long term commitment. If you want it to survive, you need to care for it.
