Python 3 is fine (sealedabstract.com)

For a man struggling years with Matlab/Octave and Scilab, I decided one year ago that Python3 is better. And never looked back even if packages had a delay in catching up. Julia is good. I will re-evaluate in 1-2 years.

Python 3 will be better and better with more and more project porting to Python 3.
