A few weeks back I surveyed my 3,500 members at PyDataLondon (London-based Python data scientists) about their Python version usage. At work 60% use Python 2.7, 33% use Python 3.4+. At home 44% use Python 2.7, 49% use Python 3.4+. I'm predicting 50% at-work usage of Python 3.4+ this time next year for my London community: http://ianozsvald.com/2016/06/20/results-for-which-version-of-python-2vs3-do-london-data-scientists-use/ http://ianozsvald.com/2016/06/20/results-for-which-version-o... Note - I'm the co-chair for PyDataLondon (and the local conference series). I regularly poll my monthly meetup audience to see how many folk upgrade each month. Normally 1-10 per month stick their hand up, nobody sticks their hand up if I ask "how many downgraded from Python 3 this month?".

Many people use Python 2 for the sole reason it's the default system Python. I assume a lot of them will instantaneously move to Python 3 the moment typing "python" on the command line will invoke the Python 3 REPL. All my python 2 only code explicitly invokes python 2 on the shebang line.

  Though, more likely they'll find that typing "python" returns "command not found", and in that case they might find it easier to just type apt-get/dnf install python.
