Last night was the September gathering of the Sydney Python Users Group.
Then Vaughan Allan (@vornstar) gave a presentation on TDD with Python. It was a good introduction of what TDD is and the benefits. Slides are here. Dylan Jay followed this with a case study on how he used TDD for Google App Engine project. Q&A became a vibrant discussion about the pros and cons of TDD, best practices etc which proved to me how valuable the monthly meetups are.
Thanks to Google for the venue, food and drink.
