Hi,

I'm opposed to adding methods to bytes for this, as I think it goes
against the reason for the separation of str and bytes in the first place.
str objects are pieces of text, a list of unicode characters.
In other words they have meaning independent of their context.
bytes are just a sequence of 8bit clumps.
The meaning of bytes depends on the encoding, but the proposed methods
will have no encoding, but presume meaning.
What does b'%s' % 7 do?
u'%s' % 7 calls 7 .__str__() which returns a (unicode) string.
By implication b'%s' % 7 would call 7 .__str__() and ...
And then what? Use the "default" encoding? ASCII?
Explicit is better than implicit.
I am not opposed to adding new functionality, as long as it is not
overloading the % operator or format() method.
binascii.format() perhaps?
Cheers,
Mark.
