This is correct python3.org  is only setup for email.
Use the host and dig commands to check for yourself.

Compare

$ host python.org 

with

$ host python3.org

And compare:

$ dig -t A python.org 
$ dig -t MX python.org 

with

$ dig -t A python3.org 
$ dig -t MX python3.org

ping script

[Byung-Hee HWANG]

simple ping check script with python3 (Python 3.9.2)
tested under Debian 11 Bullseye:

soyeomul@penguin:~/gitlab/test$ ./fping.py localhost
ok
soyeomul@penguin:~/gitlab/test$ ./fping.py python.org
ok
soyeomul@penguin:~/gitlab/test$ ./fping.py python3.org
python3.org: No address associated with hostname
something is wrong...
soyeomul@penguin:~/gitlab/test$
