The docs suggest creating your own package or building and installing 
from source:
https://docs.python.org/3/using/unix.html

To install from source, use ‘make altinstall’ (instead of ‘make 
install’) to avoid shadowing your system Python version. The alternative 
interpreter should be qualified with <major>.<minor> version, e.g. 
python3.11

Depending on the package manager used by the distribution, 
‘checkinstall’ could be used to build from source and install as a 
package without rolling your own.

On Ubuntu check out the deadsnakes PPA:
https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

Or use python-build from pyenv to install to a custom location:
