Python and OpenOffice.org
OpenOffice.org 3.1 ships with the Python scripting language, version 2.6.1. Older OpenOffice.org ships with Python version 2.3.4. This Python distribution comes with the Uno module, which connects the UNO API to the python scripting language. To run this version of Python on Linux, you can go directly to the OpenOffice.org PATH. And as one would expect with any distribution of Python, OOo-Python can be run from the command line as well.
If you already have a separate Python 2.6 installation, you can import the uno module (the Python-UNO bridge) to it using these instructions.
If you already have a different version of Python installed on Windows, you can also access the UNO API using the COM bridge instead of the Python bridge. Requires the add-on pywin32 module so Python can talk to COM. Note that while the UNO API is uniform, the implementation by the two bridges is slightly different, so the syntax required by each is also sometimes different.
Where is the IDE ?
OpenOffice.org's IDE doesn't support Python, so development has to be done from another editor that does. Any volunteer for a binding is welcomed.
Tips & Tricks
Here is some useful information about using python in OOo.
If you launch a python script, any error will silently break the execution, making your extension hard to debug. To change this behaviour, one can change the LogLevel .
Have a look in /path/to/ooo/program/pythonscript.py and replace LogLevel.use = LogLevel.NONE with LogLevel.use = LogLevel.DEBUG .
There are also currently-undocumented environment variables that tell the pyUno bridge to log every call. Set the environment variable export PYUNO_LOGLEVEL=ARGS . The output may be a little hard to read, but helpful nonetheless.
Note that his applies only to Linux. For Windows, you need some more switches, and the output gets written to files (there is no stdout on windows :-( ).
There are still some error messages that won't appear in these logs; this will improve in the near future (cws pyunofixes4). Once the cws is integrated, I will document these switches on the official pyuno site.

Python specific information for Extension creation
To create extensions for python, it is important that you have enough familiarity with the UNO components, as well as with packaging your code for easy distribution through the OpenOffice.org package manager. Please check the tutorials to learn how to component-ize your code, and how to deploy remote scripting through a service implementation.
