So far I received 7 different alternative suggestions, both pure
numbers & mixed int/str approach, which is great because I learn far
more than I would expect given that the subject discussed is a tiny,
little string to digit sum program. I play around with each piece of
code I receive, I take notes and I memorize as much as possible for
upcoming challenges. Although it's sometimes confusing to me as a
novice to programming, I actually like the idea that one and the same
task can be solved in different ways in Python (it spurs my
creativity). And, again: Thank you all for your elaborate and
extremely helpful responses!
