Python 2 is going to be end-of-life in early 2020. That's in about half a year, about time to start moving your production projects over to Python 3 if not done so. In this talk, Gary will share how he migrated a decade-old Mozilla project (funfuzz) over to Python 3, tools used, as well as advice to help you do the same to your projects.
