I also don't understand why we can't use %b instead of %s. AFAIK %b
currently doesn't mean anything and I somehow don't expect we're likely to
add it for other reasons (unless there's a proposal I'm missing?). Just
like we use %a instead of %r to remind people that it's not quite the same
(since it applies .encode('ascii', 'backslashreplace')), shouldn't we use
anything *but* %s to remind people that that is also not the same (not at
all, in fact)? The PEP's argument against %b ("rejected as not adding any
value either in clarity or simplicity") is hardly a good reason.On Thu, Mar 27, 2014 at 10:20 AM, Guido van Rossum <gu...@python.org> wrote: > Actually, I had ignored this discussion for so long that I was surprised > by the outcome.
