Idk how to start the coding I don’t see it
You should download a code editor (e.g. VS Code), install the related extensions from the marketplace, create a .py file and start tinkering around. There are plenty of online resources to teach you Python, such as Learn Python and W3Schools.
Personally I have good memories of starting with a very bare-bones approach, with just a terminal, and writing python scripts in notepad.
Then from the terminal
cd ~/path/to
python my_script.py
If you want to go that route on Windows you could install Anaconda I think? It comes with a terminal emulator.
