To restate what Peter is presenting: transforming the control flow
structure of the program (if statements) is the key.  That is, we take
that control flow structure and rephrase it as _data_ structures
(lists, dicts).

You'll also hear the term "Data Driven Programming" or "Table Driven
Programming" to refer to this idea.  For example:


It's a core idea, and definitely worth practicing by fixing the
program.  You'll see all that control flow structure dissolve away.
