they can suggest 3.11 and there might be a good reason for that, but you 
should not worry about something as specific as "3.11.1" - use the 
latest release in the 3.11 series.

I think it's been covered in previous replies, but to be even more explicit:

*Don't* re-run the Python Installer.  Windows will sort of "remember" it 
and may present it to you when you try to launch, and for some reason 
the core team appears unwilling to name it something less ambiguous, 
like python_setup, despite that having been requested several times over 
the years.  You would probably do well to just remove  that file (for 
the case you've described, python-3.11.1-amd64.exe).

Python itself is a command-line tool. You can launch python from inside 
a command shell (Windows Terminal is actually a good choice, even though 
it's not installed by default), usually by typing "py" (unless you 
somehow declined to install the Python launcher), or you can navigate to 
it through the start menu.  You will, however, probably want to use some 
sort of editor to work inside or it gets quite tedious.  You can use the 
included IDLE also via the start menu, or install one of the many free 
choices available.  Your school's curriculum may well guide you here, if 
you want to be able to follow along exactly with classroom presentation, 
screenshots, etc.
