Not mentioned yet, but maybe worth considering, might be to dip into
the way back machine and start with a much earlier version of Python,
maybe 1.5.2 or 2.0. The basic structure of the system is still there,
but without much of the complexity which came along with more recent
changes. No Unicode, types and classes were still separate, the
bytecode interpreter was much simpler, many types were simpler.

Once you have the basic foundation, pick something which has changed
significantly, and make a deep dive into it.
