It doesn't seem to be widely known that Python 2.7's dict has viewkeys()/viewvalues()/viewitems() methods which implement Python 3 dictionary views. Thus, an alternate (or concurrent) proposal could be add these aliases to the Python 3 dictionary type. At any rate, the PEP should mention these methods' existence. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
