I don't know what that is; can you give a link to what you're referring
to?

Is that Python code? If it is, I've already demonstrated that ‘0xDD’ in
Python code *is* ‘221’. They're different representations that compile
to exactly the same object.

Right, which you can do by creating an integer as you've already done:

    >>> foo = 'DD'
    >>> int(foo, 16)
    221

because that *is* the number ‘0xDD’:

    >>> int(foo, 16) == 0xDD
    True

So don't do that; use the integer.
