In adding the ability to refer to field values using dbfFile.field
notation, I learned how to use __getattr__ and __setattr__ . After some
trial and error, I got it working. But as part of my trials, I added
some print statements to debug stuff. The ones I added to __setattr__
work as expected, but the one in __getattr__ seems to get called just
under 1000 times for every __getattr__ call!
Something is obviously not right here - but...

Hi,
I use urllib2 to download a redirected url and I get an exception from
the bowels of urllib2. It seems that urllib2 implements some super
sophisticated self check and tries to control the access to attributes
using lots of calls to hasattr(the builtin function) and a custom
__getattr__() on the Request class that perfroms some checks and raises
an AttributeError if it's not happy. The problem is that hasattr()
according to the docs is...

Just wondering about this behaviour, why is it this way?

Now I have to design a class that overload __getattr__, but after
that, I found the __repr__ have been affected. This is a simple
example model:

self.x = 1
def __getattr__(self, attr_name):

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...

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...
