Python 3.11 is the default right now (and has been for some months now.) 
You should follow the python upgrade procedure (there should be a news 
item for this, you can view those with "eselect news list".)

After the upgrade, it might be easier to block new python versions until 
Gentoo switches the default version again later. This has been a 
mainstay in my packacke.mask for ages now:

   # Prevent a shitload of different python versions from being installed
   <=dev-lang/python-3.10
   >=dev-lang/python-3.12

(Obviously the versions are gonna differ over time.)

I don't set PYTHON_TARGETS nor PYTHON_SINGLE_TARGET. Currently, the 
defaults are:

   PYTHON_SINGLE_TARGET="python3_11"
   PYTHON_TARGETS="python3_11"

When the default Python version changes, this is usually announced 
through a portage news item and you'll get a notification about it when 
you sync.

If you really want to stick to 3.10, you can try setting the above vars 
for portage. You can do this in your package.use:

   */* PYTHON_TARGETS: -* python3_10
   */* PYTHON_SINGLE_TARGET: -* python3_10

However, 3.11 is the current default for a reason. Maybe some packages 
really require it, and thus you will end up with both 3.10 and 3.11 
installed. If you just want a single version installed, then it's a good 
idea to not go against the current portage default.
