Hi! I'm a new hand of ArcPy knowing little about how to interpolate point samples to the surface by Python scripting with new approaches the ArcGIS has not provided. I want to learn how to achieve it by imitating the methods toolbox have used ,such as the process of IDW. But the only thing I can find is a ready-made function(such as Idw (in_point_features, z_field, {cell_size}, {power}, {search_radius}, {in_barrier_polyline_features})) which can't help learn Python scripting. So, where could I find Python scripting of existing interpolating method which can help Python learning in toolbox or ArcPy?
