Hi, Firstly an apology -- I only just noticed your original code was Python 3 -- my example was Python 2, so there would be some changes required to make the example work on Python 3...

Yes, that's usually a good idea. > I will try and write some values to a file as I am struggling even doing this. > > > TypeError: 'str' does not support the buffer interface > > TypeError: 'tuple' does not support the buffer interface Could you post the lines of code that generates this exception and the full stack trace that goes with it? Nonetheless, having re-read your question and having googled a bit, it seems that your problem might be related to Python 2 vs. Python 3, see here: http://stackoverflow.com/questions/24294457/python-typeerror-str-does-not-support-the-buffer-interface In short: In Python 2 you are expected to open the CSV file in binary mode ('wb'). In Python 3 this should be text mode as per the above question, else you'll only be able to write "bytes" streams, hence the "buffer" interface errors. If you've perhaps been cribbing/using Python 2.x examples and documentation while in fact using using Python 3, then that would help explain the confusion...?
