Is there a way to mark string literals so that 2to3 automatically

Type "copyright", "credits" or "license()" for more information.
>>> b=b'abc'
>>> b
'abc'
The b prefix does nothing in 2.7. It was specifically added for this type
of porting problem.
More precisely, it was added in Python 2.6, so older Python versions will
consider it a syntax error.
To support older Python versions, you need to write your own wrapper
functions for bytes literals that do nothing in Python 2 and convert the
literal back to a bytes literal in Python 3. That's ugly, but there's no
other way to do it.
