Getting Started With Python Programming (QGIS3)¶ QGIS has a powerful programming interface that allows you to extend the core functionality of the software as well as write scripts to automate your tasks. QGIS supports the popular Python scripting language.

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.

QGIS provides a built-in console where you can type python commands and get the result. This console is a great way to learn scripting and also to do quick data processing. Open the Python Console by going to Plugins –> Python Console.

PyQGIS refers to the Python environment within QGIS. It allows users to automate workflow and extend QGIS with the use of Python libraries. But it’s not only Python core libraries. You can also leverage thousands of third-party libraries adding functionality with scientific and data analysis.
