In Python 2, b'A' makes a str.

In python 3, b'A' makes a bytes object, and array of small (8-bit) ints.

Element 0 of that array _is_ the byte 65, an integer.

So:

  Python 3.3.3 (default, Nov 23 2013, 13:21:35)
  [GCC 4.2.1 Compatible Apple Clang 4.1 ((tags/Apple/clang-421.11.66))] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  >>> x=b'A'
  >>> x
  b'A'
  >>> x[0]
  65
  >>>

Just move to python 3 for your code and you'll be better off for what you
seem to be wanting.
