To the best of my knowledge, `is` has the same meaning in all variants of English (although there are sometimes differences in grammatical form, e.g. "this be that" versus "this is that"). It is a very old word, and such old words tend to have astonishingly stable semantics and irregular spelling. https://en.wiktionary.org/wiki/is#English https://en.wiktionary.org/wiki/be#English -- Steven -- https://mail.python.org/mailman/listinfo/python-list
