They're completely trivial and one-off scripts each time I teach.
Basically I just make some simple Python data structure for the grades,
fill it in in a single text file, then write a little program to compute
grades based on it. It's really been written as throw-away code.
I have sometimes wondered about doing something more systematic
with other people that would be more re-usable. This is a good
thread to discuss what properties such more general code would
have, e.g., things like: easy report generation, easy reading and
writing data to a standard csv's spreadsheet friendly format, etc.
