I look for ideas in such articles. It is better to read articles with code from authors who specialise in it.

Python is terrible for careless attitude to variables - it is hard to read it at all, because there are many variations of doing the same thing by different methods.

Well, depends on the time spent on the article. I don't have a steady income, so as an option when other things are done, it can be an interesting source of income. Although I write at least a month article - almost every day spending time to work on it - probably need to change the approach.

I have a different approach. I don't write articles. I just share the material I have. I add letters to the code. To develop the MO theme, so to speak.

Python is the simplest and most understandable language!

Well... here's an example - I've been stumped for a long time - I don't understand why the code doesn't work properly.

import pandas as pd

#  Исходные данные
Input_Data = pd.DataFrame({'A': [1, 2, 3],
                           'B': [4, 5, 6]})
Input_Info = pd.DataFrame({'C': [7, 8, 9],
                           'D': [10, 11, 12]})

#  Выбираем строку для объединения (предположим, Stroka = 0)
Stroka = 0

#  Объединяем строку из Input_Data и Input_Info
row = pd.concat([Input_Data.iloc[Stroka], Input_Info.iloc[Stroka]], axis=1)

print(row)

We should get a row with columns ABCD in a row, but we get

     0     0
A  1.0   NaN
B  4.0   NaN
C  NaN   7.0
D  NaN  10.0

It's the code's fault, no other way round)

that's in the pandas documentation, please. Or chatgpt.

Pandas is not python, but a pluggable lib.

I already gave a link to it on my channel, use it!

Yes this is an example from ChatGPT - it didn't work - went digging around the internet - and didn't find the answer... but I did find similar code that probably used to work.

For me these libraries are all python as they are too popular.

Then I started to pester ChatGPT in another way - what's wrong with this code, he denied it - everything is fine, then he gave me some strange variant of its writing, which worked, and I asked him why it works, and he started to apologise - he got it wrong and it shouldn't work....

Many shells for launching trained models have already been invented, but I can't get my hands on them yet, and there are not many large models in Russian.

If you needed two lines instead of one, the code would work correctly....

Many shells for running trained models have already been invented - but so far the hands do not reach, and there are not very many large models in Russian.

There is a choice of several recent models and all for free from one application.

Well, I don't keep all the nuances in my head either. I use the documentation.

Yes I know - I saw a video clip - they make a lot of different shells nowadays.
