PyQGIS For Adding Layer Under SubGroup

Taming Your QGIS Layers: A Human’s Guide to PyQGIS Subgroups

Ever feel like your QGIS project is a chaotic jumble of layers? Yeah, me too. That’s where PyQGIS comes in – it’s like having a superpower for automating GIS tasks and bending QGIS to your will. One of the most useful tricks in its arsenal? Programmatically organizing your layers into subgroups. Think of it as Marie Kondo-ing your GIS data. This guide will walk you through adding layers under subgroups using PyQGIS, making your projects cleaner and your life easier.
