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 socket standard library - would be great. Just for the records, I came here because of this feature request: https://github.com/giampaolo/psutil/issues/928 Regards, Thomas Güttler PS: For some strange reasons I received only some mails of this thread. But I could find the whole thread in the archive. Am 20.06.2017 um 04:05 schrieb INADA Naoki:
Namedtuple in Python make startup time slow. So I'm very conservative to convert tuple to namedtuple in Python. INADA Naoki <songofacandy@gmail.com>

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? (First open an issue stating that you're interested; point to this email from me to prevent that some other core dev just closes it again.)

AFAIK the socket module returns plain tuples in Python3:
https://docs.python.org/3/library/socket.html
Why not use named tuples?
For technical reasons: the socket module is mostly implemented in the C language, and define a "named tuple" in C requires to implement a "sequence" time which requires much more code than creating a tuple.
In short, create a tuple is as simple as Py_BuildValue("OO", item1, item2).
Creating a "sequence" type requires something like 50 lines of code, maybe more, I don't know exactly.
