With Python 3.x the s.before is of bytes instead of str. You need to convert from bytes to str:
v = s.before.decode()
print(v)
The default encoding for decode() is utf-8. You need to specify the correct encoding if it's not in utf-8. E.g.:
v = s.before.decode(encoding='latin1')
See Python3's Unicode HOWTO for more details.
