Hi there,
I'm learning Python at the moment and trying to grok the thinking behind
it's scoping and nesting rules.
I was googling for nested functions and found this Guido quote:
(http://www.python.org/search/hypermail/python-1993/0343.html)
"This is because nested function definitions don't have access to the
local variables of the surrounding block -- only to the globals of the

greetings....
in a python nested class is it possible to change the value of the
parent class's variable without actually creating an instance of the
parent class, consider this code:
class mother:
x=0
def __init__(self):
self.x=1

Hi,
Nested classes only seem to be able to access static members of the
surrounding class :

Is it not possible to declare a nested class in a seperate file from
its "parent" class -- i.e. in a similar way to the idea of spreading

I've got a class in which I want to implement a property
that operates like an indexer, for the various colors
associated with the class.
For instance, I want to be able to do 'set' operations like
MyClass.MyColors = Color.Green
or, a 'get', such as
Color forecolor = MyClass.MyColors;
I want to use an indexer so I can take parameters, such
as the color type (e.g. "Foreground", "Background" etc.).
With a single member function I couldn't...

I've almost completed building a Model-View-Controller but have run into a
snag. When an event is fired on a form control I want to automatically
updated the "connnected" property in the Model. This works fine if all of
the properties are at the top (root level) of the model but I'd like to keep
them in nested classes to organize them better.
So, for example, part of my data model looks like this (simplified) :

Hi...
Maybe I'm just being especially obtuse today, but I've been perplexed by how
some of the protection levels have been working with nested classes in C#. I
have a parent class that wants to be able define sub-object to return to
consumers but wants to really clamp down on how much is exposed to the
consumer - for example, I wanted to make consumers unable to instantiate the
sub-objects on their own.
Originally, i'd hoped...

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...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
