There are three books involved, two of them are Python. The original SICP, the CS61A Python version of SICP (top poster in this thread linked to it, no longer in use), and the current version of the text (also Python) that I linked.
(The title of the submission seems to have changed, earlier it mentioned both Scheme and Python.)
The link you provided links to a series of pages about (mostly) Python, some SQL and a touch of scheme. Interestingly, it doesn't talk about using scheme as a programming language as much as using python to create interpreters which interpret a small subset of scheme.
I think most people would look at that corpus and say "that's a Python text."
It’s the current version of the textbook for the current version of the submitted course (CS61A). I don’t understand the point you are trying to make. It was an appropriate addition to the discussion.
