1. Download, edit, and compile Python source code. Perhaps substituting '!' for 'not' in the grammar file will suffice. I do not *think* that this would conflict with '!=' digraph. 2. Realize that code for your custom Python will not work anywhere else if it does contain '!' with that meaning. -- http://mail.python.org/mailman/listinfo/python-list
