Not long ago I've tried to find out what are the most popular versions of Python available. I've started by asking people heavily involved in the Python world. Statistically irrelevant, but the majority of answers I've got back were: 1. production systems: 2.7.x 2. old maintenance mode: 2.6 3. some 3.x I've also tried asking the PSF, hoping that they might have more data. They pointed out to the download page: > "The current production versions are Python 2.7.3 and Python 3.3.0" A statistically relevant survey would need to take in consideration: 1. what major Linux distributions include as the default Python version 2. what versions hosting providers support by default 3. the percentage of Python libraries that work with Python 2.7 and Python 3.3 A lot of effort would be needed to pull together all these details, but I think the Python community would benefit from having this data around (even if some might find this detrimental to the advance of Python)
