Installing any arbitrary python version is a rather simple affair on most platforms. On windows you simply run another installer, and on linux you can usually install a package for a specific version. Once you've got the right python version somewhere on your system you can start creating venvs. Of course there are tools out there which will automagically download the right python version when creating a venv but in my opinion that's neither easier nor harder.
