Today's Gratitude Item: Solving a tricky problem. One of my students emailed me his broken code and I managed to fix it. There were multiple issues with it which tell me exactly where he is in terms of understanding how to code in Python. Being able to hunt down and fix all the mistakes was remarkably satisfying. It also gave me an insight into how to teach the topic better next time around.
