Adaptation notes. Reading rewritten in our voice. The worked module is a small Iowa State "gradebook" toolkit. Because the in-browser sandbox runs the student's file as a single program, the exercise has the student build the module's functions and constants; the hidden tests import that very file as a module (via importlib) and exercise the public names — exactly what a second file would do.
