if you don't want the newly-installed version to be the default. This is an absolute requirement on Ubuntu (for example), as if you replace the default version of Python you __will__ disable/break your OS (e.g., see [How to Install Python 3.8 on Ubuntu|https://tech.serhatteker.com/post/2019-12/how-to-install-python38-on-ubuntu/]). On a Raspberry Pi this isn't so far as I have seen a problem.

In the above directions, replace "3.8.5" above with whatever version you want to install. You can browse the directory of available downloads at: [https://www.python.org/ftp/python]

You must be patient. On a Pi 4, this can take a long time; on a 3 B+ a very long time. On a Pi Zero basically overnight.
'nuff said (in the title):
{{{
python3.8 -m pip install foo
}}}

If you're logging into your Pi remotely to do the upgrade, it's interesting to run a second ssh session with {{top}} or {{htop}} running, to watch your Pi's processors working very hard.
