OK, I want to scan a file for lines matching a certain regexp. I'd
like to use an assignment expression, like
for line in file:
if (g := re.match(pat, line)):
croggle(g.group(1))
Since there are no assignment expressions in Python, I have to use a
temp var. That's a little more messy, but bearable:

It has been pointed out to me that various C++ books disagree about
the relative precedence of ?: and the assignment operators.
In order to satisfy myself about the matter once and for all,
I looked at the grammar in the C++ standard. The relative fragments
are as follows:
conditional-expression:
logical-or-expression
logical-or-expression ? expression : assignment-expression

It seems to me that I cannot assign objects of a class which has a constant data
member since the data member cannot be changed once the constructor calls are
completed. Is this the way it is meant to be? Am I not suppose not to have any
constant data member if I am going to have the assignment operator working for
the class?
Or am I missing something here and there is something I need to learn about?
Clear, easy to understand...

Hello All,

Its not just this one either try this:
1.001 - 0.001 = 0.999999999999989

I do the following. First create lists x,y,z. Then add an element to x
using the augumented assignment operator. This causes all the other
lists to be changed also.
But if I use the assignment x=x+ instead of using the augumented
assignment, the y and z lists do not change.
Why is that?
This does not happen when I work with integer data type for example, as
shown below.
Thanks for your help

anyway, my question:
I want to start doing math only for learning the following skills:

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,...

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...
