After getting back to work after having the Flu, I have been very busy. I have only played one small STT on Titan in the last four weeks and have barely looked at the Python Challenge.
However in the last week I have managed to find a few moments to play with Level 30 of the challenge and with the help of hints from Bornedbored and collaboration with Nic, from the Python Challenge Forums, I have finally managed to complete this level. This level was not the most enjoyable by any stretch of the imagination and I am glad to see the back of it personally. Anyway here is the ROT13'ed solution:
