Python 3 is killing Python

[Fabien]

My two cents as a new pythonista and a scientist: isn't python2 killing 
python? This old stuff is everywhere in the tutorials, docs, etc. and 
this is quite annoying. When I download a python notebook, the first 
thing I have to do is to translate it to py3. Which is not an easy task, 
given the fact that I am the tutorial *user* and am supposed to learn ;)

Side note: Debian/Ubuntu/Mint announced the total migration to python3, 
which is good but still work in progress:
