Step on no pets (especially pythons)

Pleased with the symmetry of the last Python Quine, I decided to try for a different kind of symmetry. Here is the first, as far as I know, bytewise palindromic python quine:


#"""
d='print \'\\n#\\"\\"\\"\\nd=%s\\nexec d\\n\\"\\"\\"\\nd cexe\\n%s=d\\n\\"\\"\\"
#\'%(`d`,\'\'.join([`d`[-x] for x in range(1,len(`d`)+1)]))'
exec d
"""
d cexe
'))])1+)`d`(nel,1(egnar ni x rof ]x-[`d`[(nioj.'\'\,`d`(%'\#"\\"\\"\\n\\d=s%n\\e
xec dn\\"\\"\\"\\n\\d cexen\\s%=dn\\"\\"\\"\\#n\\'\ tnirp'=d
"""#
