This guide will demonstrate how you can use python in qgis to load, filter and manipulate spatial data. you will learn where to find the python console and how to write scripts in the editor. also, you will use the console to filter data layers for specific field values or using expressions. In this chapter, we will look at what is involved in adding functionality to a pyqgis application so that the user can select and edit geospatial features. in particular, we will examine:. Honestly, i am a pretty novice python user and far from a qgis api expert. even still, i have figured out some tips and tricks that i wish i had known when i was learning the ropes and am attempting to synthesize this information, which i have scraped from many sources, all in one place. In the following, we provide a brief introduction to the api so that you are able to perform standard operations like loading and writing vector data, manipulating features and their attributes, and performing selection and geoprocessing operations.
