OK. The best I can say is that you seem to think very differently about
your code than I do.  Re-implementing the logic of iteration just so you
can make the two end conditions look similar seems like a very bad
trade-off to me.  It adds more lines, and more names, and as Steven
points out, more opportunities to introduce errors.

I'm not sure what part of Python you are putting in the "bad" category.
This example didn't involve for/else, so are you saying that break statements
inside for-loops are a bad part?

IIRC, this started as a comparison of Python's for loops and C's.  Do you
also write C for-loops as while statements if they have a break in them,
to make both of those end conditions similar?

I'm not trolling, I'm trying to understand your unusual approach.
