Hello,
I'm a newbie Python user, a systems administrator - I've been trying
to switch from Perl to Python for administrative tasks - and one thing
I cannot understand so far is why I need the special 'self' (or anything
esle) argument in class method definitions. I might have missed an
explanation in the docs, a quick Google search did not help. Is there
somewhere on the web you could direct me to?
Thanks,

Hi all,
I was using Tkinter.IntVar() to store values from a large list of
parts that I pulled from a list. This is the code to initialize the
instances:
def initVariables(self):
self.e = IntVar()
for part, list in info.masterList.items():

Hello,
I am having trouble with throwing class instances around. Perhaps I'm
approaching my goals with the wrong solution, but here's nevertheless a
stripped down example which demonstrates my scenario:

Is there a way to discover the original string form of the instance that
is represented by self in a method?
For example, if I have:
fred = C()
fred.meth(27)
then I would like meth to be able to print something like:

I want to use the LRU decorator posted at
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/498110
on a class method. However, it complains about missing arguments. The
missing argument is `self`. I could use @classmethod but what I really
need is an instance method. I don't see how and was hoping someone else
might know the way.
Here is an example with taking that recipe as lru.py

Hello everyone,
I had read somewhere that it is preferred to use
self.__class__.attribute over ClassName.attribute to access class (aka
static) attributes. I had done this and it seamed to work, until I
subclassed a class using this technique and from there on things started
screwing up. I finally tracked it down to self.__class__.attribute! What
was happening is that the child classes each over-rode the class
attribute at their level,...

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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 launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
