And there's a distinction between strings and symbols in Lisp that could be approximated in Python by defining an empty class for each desired symbol. But since strings are used in the Python example, they should be used in the Lisp one, too. That written, there's not much benefit in doing this in a Python program, and you actually lose one of the advantages you started out with: Like Lisp, the Python syntax is readable Python. Unlike Lisp, there's no reader that will give you the original structure from its string representation without having to also evaluate it as code. Lispifying it doesn't bring that advantage unless you also implement a reader, and even then you might be better off convincing some insider to endorse a Python analogue to JSON. But that insider would probably tell you to use JSON, ignoring the lack of distinct array/tuple types in JSON, or he'd tell you to use Pickle, ignoring the fact that it's a binary format. Norvig was coping big time. He even called Python an "acceptable" compromise between what Lisp delivers and whatever it is that's supposed to be good about Python that it didn't directly copy from Lisp.
