I am new to Python and I am attempting to retrieve data from a database and
I would like to place this data into a nested dictionary. After placing the
data into a dictionary, I would like to loop through the data using for
loops. How would I do this? The format that I am attempting is:
Select data ...
Get data ...
Place data into a nested dictionary

I am writing a program to do some reliability calculations that
require several nested for-loops. However, I believe that as the
models become more complex, the number of required for-loops will
increase. Does Python have a limit on the number of nested for-loops?
Thanks.

Hello.
I am working my way through Zhang's "Teach yourself C in 24 hrs (2e)"
(Sam's series), and for nested loops, he writes (p116) "It's often
necessary to create a loop even when you are already in a loop." Then he
goes on to portray a contrived example that doesn't tell me under what
conditions a nested loop might be favoured as a solution? i.e. what are
nested loops useful for? What kinds of algorithms are served by nested
loops?...

Below you will see an example of a nested conditional expression that
this colleague of mine loves. He claims that it is more efficient that
a multi-level if-else-if structure. Moreover, our complexity analyzer
tool supposedly does not pick it up. Is it really more efficient?
Personally I find this coding style extremely cryptic, misleading and
error-prone.
I believe that I have removed all traces of proprietary-ness from this
coding...

The above link shows that C# is 450% slower on something as simple as a nested
loop. Is this because .NET is inherently slower or does the C# compiler merely
produce code that is not as well optimized as the C++ compiler?

I writing some documentation and I want to describe a common code structure
which is used to step through all the items in a collection (e.g. each file
in a subdirectory) while applying more and more restrictive filters so that
only the desired items can fall all the way through. This method is so
obvious and common it must have a name. What is it or at least, what is the
best (short) way to describe it?

Hi,
in a nested do-while-loop structure I would like to "continue" the outer
loop. With goto this should be no problem in while-loops. However, for
do-while I cannot get it to work (without a strange workaround construct):

Hi,
Can anyone help with this problem with setting up nested structures
and initializing them for use.
I have created several structs and placed them in a super struct that
I will then pass to some functions. I have defined them in the
following manner:
typedef struct trans Transient;
typedef struct sats Satellites;

ONU (Optical Network Unit) is one of the key components for providing high-speed Internet services. Its primary function is to act as an endpoint device located at the user's premises. However, people are often confused as to whether an ONU can Work As a Router. In this blog post, we’ll explore What is ONU, What Is Router, ONU & Router’s main usage, and What is the difference between ONU and Router. Let’s take a closer look !

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...
