Is there anything about doing it the other way around, i.e. embed python code in Go...? I wish we could get the easy-deployment story of Go around the easy-development story of Python.

This probably isn't what you're after, but interestingly there is a Google-developed Python dialect that can be embedded in a Go program, to facilitate runtime scriptability and programmable config files:

It seems to be used by the Delve debugger for example:
