That's what I'm here for. I like loop "else" clauses, but have to
admit that (a) I rarely use them; (b) most of the time I use them, my
control flow is on the way to becoming so convoluted that I'm going to
rewrite the whole function soon anyway; and, (c) I've often misread
code that uses them, mentally attaching the "else" to a nearby "if"
instead.
I also suspect that if they weren't in the language already, a PEP to
introduce them would fail, because
still_looking = True
some loop:
if found it:
still_looking = False
break
if still_looking:
# what would have been in the "else" clause
is clear and easy to write without it.
