Here we go again. I blogged about this before but now I’m trying to do it using Python. I don’t know why this is so difficult!

I had to ask the question on Stack overflow because I’m no closer to solving it.

When I eventually find the answer or if someone helps, I’ll of course post the solution here. It’s funny, when researching this, I kept finding the blog post I wrote before. Funny but ever so slightly irritating as well because I really don’t need to read wheat I’ve written!

Updated on 8th January 2015 at 11PM: I have written a second blog post with the answer to this question here.
