Is there a good way to determine at runtime which python versions are supported? · pythonnet/pythonnet · Discussion #1724
Often we have multiple versions of python installed, although not idea. For example, most often I find python 3.7 or 3.8 in parallel with 3.9.
When I'm using pythonnet 2.5.1 I would like to flag in my UI somehow that 3.9 is not supported, so I can react, like change some paths or switch the version to 3.7 or 3.8.
I would like to make a check, get all installed python versions, and a list of the supported ones by python.NET, to exclude the unsupported ones in my app.
Is there a good way to determine this at runtime?

Thanks Victor!
Is there anything that can list, at runtime, the supported versions by python.NET?
My use case is that my app is an add-in and doesn't install python.NET itself, so I can't just hardcode a value.
One very hacky way I can think of is to try and find Python.Runtime.dll (relying on a relative path), and listing the generated namespaces TypeOffsetXY where X is the major version and Y is the minor version, for example TypeOffset37. But this is sort of a hacky way and very prone to errors.
Is there a good way of finding out what are the supported versions by python.NET, at runtime?
We could expose this as a property or function in the DLL (only for 3.0 onwards, I don't think we will make another 2.5 release).
Ok, good to know. And yes, I believe that would be a good thing to have going forward.
Thank you, Benedikt!

That would be helpful. I've just put a hard-wired check for Python <= 3.8 into my library to avoid mysterious exceptions when it runs with Python 3.10.
