It should be possible to find the version of python shipped with each 
version of macOS by looking at the tags at 
<https://github.com/apple-oss-distributions>. For example, clicking 
through to python from 
<https://github.com/apple-oss-distributions/distribution-macOS/tree/mac-os-x-1068>, 
you can see that 10.6.8 shipped with Python 2.6.1 (and some older versions).

As mentioned previously, python3 is part of the developer tools, and 
unfortunately the corresponding source doesn't seem to be available 
anywhere that I can find. I think the /usr/bin/python3 stub first 
appeared in Catalina, with the actual python installation in Xcode 11, 
and was 3.7.3 at the time, but don't quote me on that.
