Hi ! I found a workaround a while ago to update the viewer to the next frame. You want to use a *curveTool *node. In your python script before the loop create your node then execute it for frame "i" in your loop.
I don't have access to my scripts but you can refere to the Nuke python api. Don't forget to delete your CurveTool node at the end of your script.
