Python is actually in version 3, which I use. But a lot of people are still using Python 2 as some libs are not yet ported. It would be great if you can support both. Please note that Python 2 and 3 ...
I think that it would make more sense to reach out to the owners of the libraries that you are using so that they migrate their code to Python 3. As time passes, Python 2 will be used less and less and there will be fewer and fewer libraries that do not have a version in Python 3. There is not much incentive for Microsoft to add support for a dying version of a language.
