It would be helpful to know how you uninstalled it.

The message you saw looks like it comes from the installer rather than
from the Python interpreter. Try invoking Python with "py" (assuming
you are using Windows). That is the standard Python launcher that is
installed by the installer from python.org.

For the future, know that you can have several different versions of
Python installed at the same time. On Windows, you can launch a
specific version using the launcher:

py -3.11
py -3.12

And so on.

On Linux you should use the full name, such as

python3.11
python3.12

etc., depending on which versions have been installed. "python3" will
get you the version used by the system, which may not be the one you
want to use.

To install Python packages with pip, make sure you specify which version
of pip to use, like this:

py -3.11 -m pip (Windows)

or

python3.11 -m pip (Linux)

Otherwise you make accidentally install the package into the wrong
Python installation.

Sorry - - - but you just haven't given enough information so that you can
be helped.

What OS are you using?

How did you install python 3.12?

How did you un-install it?

How did you install python3.11.1?

With answers to all of the questions - - - it would be much easier to
answer you?

That’s the installer. All it does is install the software.

There isn’t an IDE as such, although there is IDLE, which you should be
able to find on the Start Menu under Python (assuming you’re using Windows).

There are a number of 3rd-party editors available that you can use when
working with Python, or you can use Visual Studio Code from Microsoft.

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.
