Wild idea, but could we avoid a new keyword by reusing one that can't go there, like except? for i in range(0,10) except (2, 8): don't know if it is actually worth it, but at least it doesn't add a new keyword. -- Richard Damon _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/EKASCDKVQT75UY7HSLYFVW62IDH7DRTU/ Code of Conduct: http://python.org/psf/codeofconduct/
