Update/Add Z values for the vertices of a polyline - How to?

For creating a polyline feature class from xy coordinates, I�??m able to follow the example python script given at the ArcGIS 10 help library...Writing Geometries.

I want to take this a step further. Assuming an existing polyline feature class has the ability to store Z values in the geometry field, how one would craft a python script to iterate the vertices of the polylines and add/update Z values to them.

As I understand it, the process would involve using the UpdateCursor and InsertCursor at the same time.  I have found an old example but I'm struggling to make sense of it.

Can anyone provide a very simple Python example that demonstrates how this could be done under an ArcGIS 10.x platform?   I just need a simple example that explains the basic concepts and steps involved.
