How can I get the Python Core course?

Stanley Nguyen , the `python core` course has included beginner and intermediate learning materials, as well as exercises for both. the modules `regular expressions` and `pythonicness and packaging` from the `core` course are currently unavailable. All other topics are covered in the current `introduction to python`, `python intermediate` or `python developer` courses (there might be some overlapping between them). the new courses also offer a better learning experience.

Those are old courses that are no longer available.
