"Office Hours" Smart Iterator Challenge

Challenge-week 2: Modular Programming

"Office Hours" style BBB web-conference with "dn" and others, starting at 1830 (and lasting for as long as there are interested-participants).

Ask questions, work on the challenge whilst others are 'around', or more generally 'talk Python'. (If you can't make this time, either request another mutually-convenient time for a BBB-call, or post a query through Meetup-messaging)
