!! Upgrading to a Newer Version of Python
To upgrade to a newer version of Python, e.g., 3.8.5:
{{{
sudo apt update
sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev
wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz
tar zxf Python-3.8.5.tgz
cd Python-3.8.5
./configure --enable-optimizations
make -j4
sudo make install
}}}
or
{{{
sudo make altinstall
}}}
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.
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.
