Jason Fried - Fighting the Good Fight: Python 3 in your organization - PyCon 2018 

Speaker: Jason Fried
Today, services built on Python 3.6.3 are widely used at Facebook. But as recently as May of 2014 it was actually impossible at all to use Python 3 at Facebook. Come learn how we cut the Gordian Knot of dependencies and social aversion to the point where new services are now being written in Python 3 while older Python 2 projects are actively migrated to Python 3. All accomplished by a small group of individual contributors in their spare time. Learn to fight the good fight and upgrade your organization to Python 3 like we did at Facebook.
