I'm looking for some resources for learning PyQGIS.
It would be interesting having a collection of books or websites that provide some practical examples for learning the syntax or accomplishing specific tasks.
Ideally, these resources should give a general guidance for both beginner and experienced users.
Where to find QGIS tutorials and web resources? is a very similar question, but it gives help for learning QGIS, and not specifically PyQGIS (in fact, it doesn't have the PyQGIS tag).
