Bill, I am confused, could you explain the first line of code. I can probably then figure out the remaining. all I need to do is find the difference of two binary numbers, converting them to decimal is easy to do. here is the first line of code from the link you sent:
# bstr_pos: only positive integers
# zero -> ''
# negative -> ''
bstr_pos = lambda n: n>0 and bstr_pos(n>>1)+str(n&1) or ''
thanks.

Jeff,
There isn't a built-in type, but it's fairly easy to do. Have a look
at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/219300 for
some ideas on how to do it. If you don't understand those, ask and
I'll try to clarify them for you.
Peace
