"I just learned language X, look at how I can fail to implement lisp in more lines of X than the original mccarthy code took to actually implement lisp" really just isn't relevant here.
I'm glad you're learning python. I'm glad you're enjoying it. I'm glad you managed to write something that you think is within spitting distance of lisp with it.
But there's no need to post it to HN. Wait until you've done something actually interesting.
