I have an application, which is an instance of a class
with a deeply nested object hierarchy. Among others one
method will be executed as a thread, which can be stopped.
Everything works fine except that when deleting the main
instance - after the thread has been stopped -
the __del__ method will not be carried out.
Tough a simple example works as expected:
>>> class A:
.... def __init__(self):

I'm __del__() to decrement a count of instances of a class whenever an
instance is deleted, and I'm getting very erratic behavior. This is
in CPython, which I am told has no problem with reference counts
getting out-of-sync with the deletion of instances. The behavior of
__del__() seems to be very sensitive to the exact sequence of
commands.
The example below is a repeatable test case. It might be possible to
simplify this further,...

After more reading it seems I have made an ass of my self on this
subject. Here is my problem at length.
I teach high school geometry. I have created a program with a
scalable graph on which to make drawings to illustrate concepts.
This is working well.

Hallöchen!
When my __del__ methods are called because the program is being
terminated, I experience difficulties in calling functions that I
need for a clean shutdown of my instances. So far, there has been
only one of these functions, and a class-local alias solved the
problem. However, now there are many of them.
Is there a way to detect whether the program is being terminated?
(In this case, I wouldn't care and return from...

I'm baffled with a situation that involves:
1) an instance of some class that defines __del__,
2) a thread which is created, started and referenced by that instance,
and
3) a weakref proxy to the instance that is passed to the thread
instead of 'self', to prevent a cyclic reference.
This probably sounds like gibberish so here's a simplified example:

I have a class that I need to do some finalization on when it dies. I
know I can use the __del__ method, but I seem to recall that it
impedes garbage collection. Is this the case?
(keep in mind that my code aims to be compatible with python 2.3 to
python 2.5)

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...

Hello
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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
