Yes, at startup time point of view.
Current Python namedtuple implementation uses `eval`.
It means we can't cache bytecode in pyc files.
For example, importing functools is not so fast and
its because

thank you! I am happy that Guido is open for a pull request ... There were +1 votes, too (and some concern about python
startup time).
I stopped coding in spare time, since my children are more important at the moment .. if some wants to try it ... go
ahead and implement named tuples for the

While we are talking about startup time, I would be curious of seeing
the overhead (python startup time, when importing socket

Aye, I don't think a Python level wrapper would be the right way to go
here - while namedtuple is designed to be as cheap as normal tupl
Namedtuple in Python make startup time slow.
So I'm very conservative to convert tuple to namedtuple in Python.

Oh, about the cost of writing C code, we started to enhance the socket
module in socket.py but keep the C code unchanged. I am thinking to the
support of enums. Some C functions are wrapped in Python.

There are examples in timemodule.c which went through a similar conversion
from plain tuples to (sort-of) named tuples. I agree that upgrading the
tuples returned by the socket module to named tuples would be nice, but
it's a low priority project. Maybe someone interested can create a PR?

For technical reasons: the socket module is mostly implemented in the
C language, and define a "named tuple"
+1 ;-)
for example to get IP address of all interfaces we have to use the third
(indexed as 2) member of "something" it is much more beatiful to get
ip_address:
*import *socket
*for *ip *in *socket.gethostbyname_ex(socket.gethostname())[2]:
print(ip)

AFAIK the socket module returns plain tuples in Python3:
https://docs.python.org/3/library/socket.html
Why not use named tuples?
