>>> type(a) == HexInt True That's what I wanted (though I don't know if that's what the OP wanted). BTW, sorry for the wasted bandwidth, didn't realize you might have such a small bandwidth that seven lines would be a hassle. We should also tell the blokes of the 'music' thread to stop it, I can imagine how mad that must get you. -- http://mail.python.org/mailman/listinfo/python-list
