> Please also mention all flags: #, +, -, '0', ' '. Is this really necessary? Can't one just refer the the str %-formatting section of the doco? By section and title to make it easy to find. I think this should just refer the reader to the str %-formatting doco for the numeric codes and their meanings, along with the flags. Otherwise the PEP will get unreadable, to no value that I can see. If we include Nick's equivalent code example, there is no ambiguity or vagueness. I'm against restricting to just %d for int too; if the current Python supports others (eg %o, %x) for str, so should this PEP for bytes. > > ``%c`` will insert a single byte, either from an ``int`` in range(256), or > > from > > a ``bytes`` argument of length 1, not from a ``str``. > > I'm not sure that supporting bytes argument of 1 byte is useful, but > it should not be hard to implement and may be convinient. I'm +0.5 for a bytes argument of length 1; while bytes are arrays of small ints, just as str has no distinct "char" type a bytes has no distinct byte type. With a string we commonly use s str of length 1 to denote a single character in isolation; the same programming idioms will get you a bytes of length 1 in situations when you mean a byte. > (You forgot "/Uhhhhhhhh" representation (it's an antislah, but I don't > see the key on my Mac keyboard?).) My Mac has one above the "return" key. Um, non-English locale? Curious. Cheers, -- Cameron Simpson <c...@zip.com.au> 16 October. I also asked Anthea how many mature oaks she thought it would have taken to build a top-of-the-line ship in Nelson's day. She guessed ten. The astonishing answer (from Brewer's) is about 3,500 - 900 acres of oak forest. She said, "I wonder what we're doing now that's as wasteful as that".
