I would rather something more like:

       def assert_compare_true(op, first, second, msg=None):
           if op(first, second):
               return
           raise self.failure_exception(msg)
           if msg is None:
               self.failure_exception("%(first)r %(op)r %(second)"
                                          % vars())
           self.failure_exception("%(first)r %(op)r %(second): %(msg)"
                                  % vars())
