With your experience with ArcGIS, the transition to QGIS should be quite rapid, and the ability to relate operations to a client will be very straightforward. Programming, or scripting in QGIS or ArcGIS just takes practice, and an understanding of the object models. I am a big fan of the books by Anita Graser, Joel Lawhead, and Eric Westra.

It exists other easier alternatives ( Fiona, Pyshp (shapefile), GeoPandas,shapely, rasterio, ...). The last module is compared to ArcPy in Comparing Map ...
