>> Given that there are significant differences between python2 and 3 Really? I don't think they are that different. If it was so different and hard to port then why have so many libraries been successfully update to support both http://py3readiness.org/ http://py3readiness.org/ You can't generalise but for the most part updating from Python 2 to Python 3 is likely to be easier and less risky and costly than doing a full rewrite in some other language. Some companies might rebuild in another language, that happens all the time - things get rebuilt from this to that. But why would a company ditch Python entirely in such a situation?
