I was so close but the program sucks

sh : python3: Permission denied

When I wrote the instructions, I was on Android 10. I am also getting permission issues on Android 14. I will rewrite the instructions to use termux instead of pydroid, but I'd recommend that you use a PC to extract the assets for now.

Ok, I am on Android 13 btw, but should I use the Terminal or the Command Prompt ?

Command prompt if you're using windows.
This is from the main zelda3 github page:
Installing Python & libraries on Windows (required for asset extraction steps)
Download Python installer and install with "Add to PATH" checkbox checked
Open the command prompt
Type python -m pip install --upgrade pip pillow pyyaml and hit enter
Close the command prompt

In your case you wouldn't close it at the end, you'd run the extract assets script
