Well, I followed Ted Ueda's blog posts about the RESTful Raylight Web Services and I translated his Powershell export sample to Python.
See the blog post Scripting Web Intelligence: the RESTful Raylight Web Services for more information.
Why Python and not Powershell ?
- Python is a cross-platform language ; you can use it on linux or unix and not only on windows ;
- Python's community is larger ;
- Python is broader ; you can use it for tasks ranging from systems automation, testing, and ETL to gaming, CGI and web development.
and of course I use more Python than Powershell 
The original powershell script export.ps1 is here. This is the Python 3 version :

Tested with Portable Python 3.2.5.1 on Windows XP and BI4.1 SP3.
It's not compatible with Python 2. Syntax and Modules are different.
PS : Sorry for the misspellings ... I skipped some English class hours at school
