Create RSS Feed (podcast) using Python

I am well chuffed with myself... Ive created my first Python program!

It recurses a directory structure and creates an RSS feed, aka podcast aka xml file from the contents. I use it to create my own podcast of audio and video files. See http://stuffaboutcode.blogspot.co.uk/2012/06/raspberry-pi-python-create-podcast-rss.html for info and source code.

I was impressed with Python although I did find it a little strange using a non strongly typed language and the indentation confused me; I couldn't get my head around how python 'knew' commands formed part of a loop or condition and not outside it - some reading on python indentation put me straight though.
