"%d" % 26 => an explicit request to convert binary integer to a base-10 
Unicode/text representation of the integer

b"%d" % 26 => an explicit request to convert binary integer to a base-10 
ASCII bytes representation of the integer

The leading "b" seems to be a very explicit request for bytes rather 
than characters to me, and seems much more attractive than the proposals 
to embed binary in Unicode by abusing Latin-1 encoding.
