Awesome work. Skulpt says it currently handles Python 2, and not the full 2.7. How long until that is fixed?
However, we run full CPython (2.7 and 3.6) on the server, so any language feature you like is just a function call away :)
As Py2 is EOL in about two years it feels risky for anything to be built on it.
The client-side code is Python 2 only for now, but we're already upgrading our Python-to-Javascript compiler to include Python 3 syntax.
