QGIS Plugins

Python support was introduced in QGIS 0.9 (2007). Today, there are several ways how to use Python in QGIS Desktop. They are covered in the following sections:

• Enter commands in the QGIS Python interactive console
• Create and use QGIS plugins
• Automatically run Python code when QGIS starts
• Create custom applications based on the QGIS API

(source: PyQGIS Developer Cookbook)

Important

All examples are QGIS 3.16 LTR compatible. Python 3 and Qt 5 required. Functionality in other QGIS versions is not guaranteed.
