The question I have is: how safe / future proof / portable is the
use of the __subclasses__ method that exists for new-style classes?

I was wondering if anyone has suggested having Python determine
a method's kind from its first parameter. 'self' is a de facto
reserved word; 'cls' is a good indicator of a class method
( __new__ is a special case ). The closest to this I could find
was the 2002-12-04 posting 'metaclasses and static methods'

Is there a purpose for using trailing and leading double underscores for
built-in method names? My impression was that underscores are supposed
to imply some sort of pseudo-privatization, but would using
myclass.len() instead of myclass.__len__() really cause Python
considerable harm? As much as I adore Python, I have to admit, I find
this to...

Hi all,
I know that this is something for which I could (keep) STFW, but I'm
mostly ignorant of the subject area and under a bit of a deadline. So
I hope people won't mind if I truncate my search and ask here.
I've tried solo and failed a few times to install various Linux
distros on Intel x86 laptops. (The software modem was always the...

Hi,
I'm familiar with static method concept, but what is the class method?
how it does differ from static method? when to use it?

I may well be being dumb (it has happened before), but I'm struggling
to fix some code breakage with Python 2.6.
I have some code that looks for the '__lt__' method on a class:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then...
