The SICP course as it is taught today at MIT had Scheme replaced with Python some years ago. I'm assuming that's what OP was referring to.

That's not accurate. They retired SICP and added a new introductory course [1] based on Python to placate the suits. Neither Sussman nor any of the other SICP folk is involved with that.

Sussman created a follow-up course to SICP [2] which is still based on Lisp and still being offered today.

My academic life would be complete after cursing the neo-SICP course.

I don't think the new course is "SICP with Python"; my impression (from talking to GJS!) is it's a different course that now uses Python. But maybe someone here has experience with it & can speak up.
