Here's my quickie response, since I don't see that anyone else
has tried to reply as of yet.  If this doesn't do it, I can
look into it further tomorrow.

The definition of __init__ always looks like this:

   def __init__(self, ...):

where ... represents zero or more arguments.  Note that the
"self" argument counts as one for purposes of the error message,
so if it says it wants exactly two arguments, that means it
really wants only one argument in addition to self.

I don't know what binhex.HexBin() looks like, but it appears to
be different than what you think.  Taking a look at the source
in python/lib/binhex.py might help you... find the __init__
method for class HexBin and you may solve your own problem
once you learn what the one non-self argument is expected
to be.

Also checking the docs again might clear things up for you now.
