This is correct python3.org <http://python3.org/> is only setup for email.
Use the host and dig commands to check for yourself.

Compare

$ host python.org <http://python.org/>

with

$ host python3.org

And compare:

$ dig -t A python.org <http://python.org/>
$ dig -t MX python.org <http://python.org/>

with

$ dig -t A python3.org <http://python.org/>
$ dig -t MX python3.org <http://python.org/>
