New submission from Thomas Kluyver: At least in CPython, format strings can be given as bytes, as an alternative to str. E.g.
>>> struct.unpack(b'>hhl', b'\x00\x01\x00\x02\x00\x00\x00\x03') (1, 2, 3) Looking at the source code [1], this appears to be consciously accounted for. But it doesn't seem to be mentioned in the documentation. I think the docs should either say it's a possibility, or warn that it's an implementation detail.
