Does a Python version of core programming concepts like Algorithms, Abstractions, OS, etc exist? Basically all the major course of Computer Science which need a programming language to grasp the concepts. Every University site I have seen has them in C++ or Java. I was so excited to do MIT 6.0 Intro course for Python and throughly dissapointed that other courses are in C or Java. Do I HAVE to learn 3 languages (even if it just skim through) to just get the basic concepts? I know of books like Learn Python the hard way, Think like a Computer Scientist and like but I guess they do not cover the above topics. Please correct me if I am being ignorant here.
