The second edition uses Python rather the the first edition which uses the Lisp dialect Scheme.
The second edition of SICP uses Scheme (there were two editions with Scheme). The new edition uses Javascript.
The second edition uses JavaScript I thought? Unless there’s also a python edition
There’s an unofficial Python version floating around, but you’re better off with one of the Scheme versions.
I like the Scheme version :) haven’t worked through the newer one. I do understand their impetus for it though (even if I personally don’t agree with it).
