I think there probably are school where the professor know c++ very well, but never bothered or too stubborn to learn/teach python.

Unlike the top 50 to 60 schools, most schools, especially research universities, don't care that much about teaching (in the U.S., at least).

This was the first serious creative coding framework I've learned 2008 or 2010 or something. I have been in this field since then. I have seen Java, Javascript, and kotlin creative frameworks but not python and I am still as surprised as you are.

The Spanish Inquisition, even.
