Converting a model into a Python script
It is also possible to automatically create Python code that performs the same task as the model itself. The code can then be used to create a console script. You can modify that script to incorporate actions and methods not available in the graphical modeler, such as loops or conditional statements.
This feature is also a very practical way of A) beginning to learn Python, B) using processing algorithms from the console, and C) creating new algorithms using Python code. You can use it as a learning tool when you start creating your own scripts.
To save your model as Python, click on the Export as Python script (
) tool. A dialog will prompt you to choose where you want to save the script. NOTE: This topic is covered more thoroughly in Chapter 10, Creating QGIS Plugins with PyQGIS and Problem Solving.
