It has been more than 5 years since Python 3.0 was released. Last week I mentioned a Python 2 vs. 3 article that pitched a reviving of Python 2.
With all that in mind, here is the 2015 Python scientists survey from Thomas Robitaille. The main results:
- 83% reported using Python 2.x ( 2.6 & 2.7 )
- 17% reported using Python 3.x ( 3.4 )
This might not be as bad as it sounds. He did a similar survey in November 2012 ( nearly 3 years after Python 3.0 ) that reported Python 3.x usage in the 1% range.
That is an average increase of 8% across the roughly two years between the surveys. If that remains constant it will be another 9 years before 2.x usage drops below 10%.
