Python2 has been completely unsupported by the Python project for over three years: https://devguide.python.org/developer-workflow/development-cycle/index.html#end-of-life-branches > But, why so many choices for versions of python? Because some Python-based programs need a specific version. If you're starting out a new project and don't have a specific version, you can probably use the latest version available, but that's not always the case. > One more question, if I install python3, does that mean that I can use all of those python3x libraries? In other words, can I use the libraries of python37* or python38* or python39? Or are these specific to those versions? Confusing, it is. Thanks. Some Python libraries will work with any 3.x Python version. Most will only work with a specific version. You definitely won't be able to use, say, the python37-requests package with a python39 installation. The "python3" package isn't a real package; it just means "the latest package of Python3 available". Right now, that means Python 3.9, but I expect Python 3.10 and 3.11 will appear at some point as well. HTH Adam
