I'll clarify this, but it looks like this: >>> len(xrange(0xFFFFFFFFFFFFFFFFFFFFFFFFF)) Traceback (most recent call last): File "<stdin>", line 1, in <module> OverflowError: long int too large to convert to int >>> basically, __len__(self): can only return an int. At least that's what I recall from the discussion. > 1. all IP addresses and networks, both IPv4 and IPv6. (IPAddrBase) > > 2. all IP addresses of both versions.

I see no need for them to be public. private they go. > > _______________________________________________ > Python-Dev mailing list > [email protected] > http://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: > http://mail.python.org/mailman/options/python-dev/python-dev%40hda3.com > _______________________________________________ Python-Dev mailing list [email protected] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
