I think what you are looking for is:
  class Test(object):
      ...
      def _setx(self, strvalue):
          try:
              self._x = float(strvalue)
          except ValueError:
              print 'Warning : could not set x attribute to %s' % (
                          strvalue)
              raise     # re-raise the exception that got us here.
      ...
