Vertex goup access in python

Hi all,
I’ve been having a hard time figuring out what is possible in scripts, re: vertex groups.

Ideally, what I’d like to be able to do, is grab a vertex group (which I’ve already assigned in the GUI) and rescale it. For whatever reason, this has been hard for me to figure out.

Is this possible? If so, does someone have a simple example?

anyone?

to follow-up my own question:

the easy answer for me was to assign the vertex group to an armature, and rescale the armature…this also worked as a shortcut for real rvk scripting in python - which seems impossible at present.
