I recently had the need to sort a large number of lists of lists, and
wondered if an improvement to the Decorate-Sort-Undecorate idiom is in
the works. Ideally, I would like to sort the list of lists (or tuples)
in place by using a simple variant of the current idiom, i.e.
list_of_lists.sort(*columns)
where *columns is a tuple that specifies the column order for the
sort. If *columns is left blank, the sort ought to work as it does...

I've written a generic sort routine that will sort dictionaries,
lists, or tuples, either by a specified key or by value.
Comments welcome!
import types
def sort(container, key = None, ascending = True):
' Sort lists or dictionaries by the specified key'
t = type(container)

I didn't think this would be as difficult as it now seems to me.
I am reading in a csv file that documents a bunch of different info on
about 200 books, such as title, author, publisher, isbn, date and
several other bits of info too.
I can do a simple sort over the first field (title as it turns out),
and that is fine as far as it gets:

Hi,
I try to implement quick sort. I sort vectors by their first value.
10 2 3 4
9 3 5 6
10 4 5 6
must be

The prog works great on maybe 500 vectors, but I have an "Aborted(core

Hi!
I want to store data (of enemys in a game) as a linked list, each node will
look something like the following:
struct node
{
double x,y; // x and y position coordinates
struct enemy *enemydata; // Holds information about an enemy (in a game)
// Its a double linked list node

Hi community,
just in case somebody needs a shellsort in c#, I rewrote the pascal
code that I found in another newsgroup. Here are both. For more
explanation on the pascal code you can search for the post on google.
I was interested in the shell sort because I needed to sort long lists
of data that may already be in order. For that reason I didn't want to
use the arraylist's sort method, which uses quick sort (and has a
worst case for...

....is to forget they are sorted???
While trying to optimize some NUCULAR libraries I discovered
that the best way to merge 2 sorted lists together
into a new sorted list is to just append
them and re-sort. The following test case demonstrates this.
It can be criticized in many ways: it only tests lists of the same
size,
it only uses "hashed" data, etcetera...
Still, my testing shows "resort everything" is consistently

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...

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...
