Unlike many distros, openSUSE provides a basic python maintained by openSUSE as part of its distro.
Many distros instead install Python using packages built and maintained in the official Python PyPi repositories.
This is why many Python packages are available using zypper and YaST Software Manager instead of running the “pip” command.
you can install any number of Python side by side with openSUSE, but generally speaking rarely supports any other version than what you already have although it can be enhanced by adding the special openSUSE Python repository for your distro.
If you want to run an altogether different version of Python, since eternity Python has had its own tool called “virtualenv” to manage and invoke multiple python on the same system, and openSUSE supported it fully.
The main thing to know is that openSUSE is co-operating with official Python efforts to deprecate Python 2 and is moving as fast as possible to encourage everyone to use Python 3 instead.
The “new” tool similar to virtualenv that manages multiple Python is Pyenv
You should be able to find pyenv using zypper or YaST Software Manager, but for convenience here is the one-click install for Pyenv https://software.opensuse.org/package/pyenv
Getting off on a slight tangent…
I don’t know if you have experience with RVM or just mentioned it because you know what it does,
But for various reasons I recommend RBENV instead of RVM and if you had any experience using RBENV you’d find a lot of similarities with pyenv because RBENV was inspired by and works like virtualenv. And then, in circular fashion when pyenv was created it supposedly adopted improvements pioneered by RBENV.
I posted a Wiki on my observations and recommendations installing Ruby using RBENV and why it might be bbetter than RVM https://en.opensuse.org/User:Tsu2/Install_Ruby
A separate comment…
I see that TW is officially supporting only Python3 3.8.3 today but that numerous people are providing 3.7 and 3.6 through builds in their home repositories…
Without knowing exactly how those are implemented, I’m guessing they’re going to change your entire system and not install side by side. https://software.opensuse.org/package/python3?search_term=“python3”
My previous post to use pyenv and install any version or number of pythons using pyenv is likely your best solution.
That’s aside from running separate virtual machines, each configured to use a different python.
