  Personally, I am not a fan of these lookma-my-interpreter-in-zero-lines stuff. Take a look at http://norvig.com/lispy.html. Bigger, but well engineered.

  I'm not entirely sure this is valid. I'm happy to be shown that I'm wrong, but it doesn't seem to support environments meaning that you couldn't implement define, making it essentially not a scheme interpreter.

  I'd be impressed by an actual implementation of R5RS in a small line count, but this just seems to be a calculator with lambda expressions and lists.

  "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.
