> As a result, solutions using strings are disallowed on problem sets and quizzes until they are taught. However, the few students who have prior Python programming experience may be tempted to find digit length without loops using a variant of the following (for our purposes) invalid solution.

Wow. this is one of the reasons I hated school. No programmatic reason what given for why a string solution couldnt be used, only an arbitrary reason. Here students may have knowledge from self teaching or whatever, but they are unallowed to use that knowledge because "reasons".

To any teacher that thinks its a good idea to punish students for thinking outside the box: shame on you. All youre going to end up doing is crushing enthusiasm and/or creating drones. Please dont.

This problem is designed more in the spirit of teaching the algorithmic thinking side of the course objectives than the Python side.

If you prefer, you can view the problem restrictions as a means to encourage students to develop a more general algorithm for solving the problem, rather than a programmatic implementation specific to Python. Hopefully this makes them seem less arbitrary.
