This is the year

Thank you for this weekly one-hour jam.

Stop the years before they roll beyond 2017. Your choice.

My submission has been made for the codeskulptor.org environment, - a Rice University online app to train in Python with a rudimentary GUI). The online link might be disabled at some point in the future, - in which case the uploaded file will work on the original website (www.codeskulptor.org). Just press the play button in the top left corner.
