Yeah but I understand GP's sentiment. As someone who writes python for my living currently, I'm a little disappointed at this because it's hard to imagine that it doesn't move further into the future the day on which we will switch our code base. I don't need to be a 3-second attention span novelty junkie to just get some pleasure out of using the latest version of the language at my workplace.
This shows a serious disconnect from reality. Discontinued support for Python 2 was never a major reason to move to python 3 for apps. Library support is WAY more important in the choice to switch. If all of the libraries worked with Python 3, there would be no reason for app writers not to switch.
