> Things are a lot better with Python 3 on Windows, and especially so with Python 3.5+. For one of my main applications py3 proved to be too slow. For my application I use: numpy, pil, tkinter, and subprocess (and process/produce/draw on screen images (at a rate of 120/sec)). I don't know WHY but with python2 it runs acceptably fast, on python3 it's 20% slower. This has been something common for me actually. I do tend to use py3 when doing any kind of data science though.
