Python --version says version 3.10.8 but error when installing whisper says I have version 3.11.2

Question

So I'm trying to install whisper from OpenAI and says I have version 3.11.2 so it can not install whisper which requires only versions >=3.7,<3.11 But I swear when I check my python version it says I have the one I need, like this:

$ python --version                                      
Python 3.10.8

Btw Before I had version 3.11.2 but I changed it with help from this post
Maybe doing the commands from this post didn't help. I'm a total begginner so maybe there is a simple solution which I don't kow. Also I'm using kali linux.
Down here is the error I have:

The problem with update-alternatives is the other versions are still installed and the programs you're using don't necessarily have to use the version you want them to. Try removing unwanted packages with apt purge.

Also, look in ~/.local/bin and ~/.local/lib to remove Python-related junk that pip leaves behind. If you didn't install anything else in those folders, they should be safe to delete. Warning: ~/.local/share does contain files you will want to keep. If you want to clean it up, you'll have to go through it manually.

pip caches downloads in ~/.cache/pip, so you can reinstall packages without having to redownload most of them.
