Install using apt-get.
sh $ sudo apt-get update $ sudo apt-get install python3 # OR python3.12
Warning: Note that for Debian, the major Python versions available are locked within a Debian release version. Therefore you must upgrade to a newer OS version to get a newer Python version. Or install Python from a different repository or build from source, but this is a custom installation which may be hard to get working or maintain, so I don't recommend it. For instance, when you install C headers or choose a Python version for your IDE, you system will not by default know to look in the custom location you've installed Python to. Using pyenv might make this easier though
