Ask HN: Anyone using Python 3 in production? (2011 Edition)

This question was asked nearly a year ago here: http://news.ycombinator.com/item?id=1464199 Is anyone now using Python 3 in production? Would you use it if you were starting over? This was discussed briefly at Google I/O this week: http://www.youtube.com/watch?v=KKQS8EDG1P4&feature=player_detailpage#t=2554s key slide: Python 3: next generation Do this if completely new Python 2: current version Most books/tutorials still here Do this if have existing software Bottom line: either is fine
