hi
i'm learning python, and one area i'd use it for is data management in
scientific computing. in the case i've tried i want to reformat a data
file from a normalised list to a matrix with some sorted columns. to
do this at the moment i am using perl, which is very easy to do, and i
want to see if python is as easy.
so, the data i am using is some epiphyte population abundance data for
particular sites, and it looks like this:

I've posted a previous question about IDEs and got some good feedback,
thanks, but it does seem that everyone has their own favourite IDE -- in
other words, no IDE was repeatedly recommended.
So, is there any data on the popularity of IDEs (most users), or is
there a chart comparing the most popular versions.
I'M NOT AFRAID TO SPEND SOME MONEY TO GET THE RIGHT IDE (but I don't
want to change products once I've chosen).

I was a C Programmer for a while. Lately started to learn Python for
one small project at school. I joined a small company where they use
C++ for development.
Can we use Python and C together ? I mean create some classes in Python
and some number crunching algorithms coded in C (for speed) and
integreate both of them.
Could somebody just show a real small example or give pointers to the
same.

Hello,
I'm planning to use Python in order to teach a DSA (data structures
and algorithms) course in an academic institute. If you could help out
with the following questions, I'd sure appreciate it:
1. What exactly is a Python list? If one writes a, then is the
complexity Theta(n)? If this is O(1), then why was the name "list"
chosen? If this is indeed Theta(n), then what alternative should be
used? (array does not seem suited for...

Hi Willy,
Thank you very much for your work.
C++ code doesnot make any serialization.
So at runtime C# code gives an serialization error at
"msg_file_s sa = (msg_file_s) bf.Deserialize(ms);"
I thought that it is very hard to memory map structure array.
I need both read and write memory mapped file at both side of C# and C++.

Hi,
I need a structure to represent a set of integers. I also need to
perform on this set some basic set operations, such as adding or
removing elements, joining with other sets and checking for the
presence of specific elements.
I think that using Python sets would be the best choice, but I also
need integers to be ordered inside the set and I've just found out
that, instead, Python sets are unordered collections.

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...

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...
