hi all, i'm relatively new to python. I find it a
pretty interesting language but also somewhat limiting
compared to lisp. I notice that the language does
provide a few lispy type nicities, but some very
important ones seem to be missing.
E.g., the multiple class inheritance is great,
but there are no generic functions (at least that
i can find). If i have classes X, Y, and Z,
and subclasses X_sub, Y_sub, and Z_sub respectively.

I promised I'd put together a PEP for a 'generic object' data type for
Python 2.5 that allows one to replace __getitem__ style access with
dotted-attribute style access (without declaring another class). Any
comments would be appreciated!
Thanks!
Steve

In the "empty classes as c structs?" thread, we've been talking in some
detail about my proposed "generic objects" PEP. Based on a number of
suggestions, I'm thinking more and more that instead of a single
collections type, I should be proposing a new "namespaces" module
instead. Some of my reasons:
(1) Namespace is feeling less and less like a collection to me. Even
though it's still intended as a data-only structure, the use cases...

What follows is a discussion of my experience with .NET generics & the
..NET framework (as implemented in the Visual Studio 2005 Beta 1),
which leads to questions as to why certain things are the way they
are.
***** Summary & Questions *****
In a nutshell, the current .NET generics & .NET framework make it
sometimes difficult or even impossible to write truly generic code.
For example, it seems to be impossible to write a truly generic

This is a little complicated to explain but I have some web services on a
machine that work great.
The problem is that I have run into a situation where I need to set up my
program to access one or another (could also be 3) different web servers to
use these Web Services. The Web Services are identical on all the machines.
I tried just changing the URL of the Web Services and cannot make it work.
I then decided to create 2 identical web...

I have an object which could be compared to a DataTable/List which I am
trying to genericify.
I've spent about a day so far in refactoring and in the process gone
through some hoops and hit some dead ends.
I'm posting this to get some feedback on wether I'm going in the right
direction, and at the same time hopefully save others from going
through the process.

Hi there,
this is what i'm trying to achieve, i have separate identical classes for
SqlClient, OracleClient, Odbc and OleDb, what i want is to create a Wrapper
class that calls any of these 4 based on the user connection.... so what i
had in mind was something like this:
Application starts and prompts user to create a database connection.

Hello everyone,
I'm writing because I'm frustrated with the implementation of C#'s
generics, and need a workaround. I come from a Java background, and
am currently writing a portion of an application that needs
implementations in both Java and C#. I have the Java side done, and
it works fantastic, and the C# side is nearly there. The problem I'm
running into has to do with the differences in implementations of
Generics between the two...

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
Here is the code in...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
