Blender 2.5 Python 3.2 Manual

Introduction

Welcome to the Blender 2.5/6 Python Manual.

Python www.Python.org is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. Python combines remarkable power with very clear syntax.
Python scripts are a powerful and versatile way to extend Blender functionality. Most areas of Blender can be scripted, including Animation, Rendering, Import and Export, Object Creation and the scripting of repetitive tasks.

To interact with Blender, scripts can make use of the tightly integrated API (Application Programming Interface). It is still under development, but is already stable enough to start using with only minor changes to be made until the first stable release of blender 2.5.

Warning Sometime between 2.56 and 2.57 releases, there was a small but important change in the Python addons API: the descriptive structure previously called bl_addon_info has been renamed bl_info… Scripts still using bl_addon_info will not be visible in the User Preferences Addons page!
