How to extract points with specific attributes from shapefile?

Hey all,

So I have a point shapefile consisting of 5 columns (ID, Description, X, Y, Z) and 99 rows.
I already imported my shapefile into my python script.
I need to extract points from my shapefile but i only need the X,Y,Z attribute for each point.

I am not sure which function to use in order to do that.

Thanks!
