Can anyone guide me through the step by step process along with the code in python to find XY coordinates through model builder, please? Thank you
There is the Add XY coordinate tool in Data Management / Features.
Its a tool, so therefore it can be used in a model.
You can also use Calculate field with properties of the geometry.
In python, see the help for reading geometries.
There is already a tool that lets you find x,y. it's called "Go To X,Y".
