have python 3.7.3 but for making runtime there is no option for this**strong text
We’ve been working toward pulling in every Python point release in a timely manner, and have been getting much better as we’ve gone on (i.e., there are far more point releases for Python 3.9 and 3.8)
We are currently prioritizing newer releases of Python for this initiative, rather than older ones.
If possible, I would recommend trying to build a runtime for Python 3.7.4, which was largely a bug fix release over 3.7.3.
Hope that helps,
