and I've tried with both python and python3 (see below versions).

Is it an issue related to my installation? Shall I upgrade and/or
downgrade?
"yield from" was introduced in Python 3.3.
Ok, that either means I need to upgrade to 3.3 or need to modify the
snippet to a suitable syntax that would work with other versions.
Considering that upgrading is something that I'm not keen to do on my
production system I believe I've only have one available choice.
It seems I could use the generator and iterate with .next() in python
2.6, at least from what I found here:

I'd be inclined to upgrade, see here
https://www.python.org/dev/peps/pep-0380/#formal-semantics for why :)
