For animated knobs you can just do
for i in nuke.FrameRange(...):
nuke.selectedNode()['translate'].getValueAt(i, 0)
The change-frame methods (nuke.frame(1234) and
nuke.root().setFrame(1234)) don't work very reliably - they are fine for
changing frame in the UI, but not for scripting.. If you needed to do
things things way, you need to make a dummy executable node like a
CurveTool, then do nuke.execute(mycurvetool, 1234, 1234) to change the
frame inside your loop
