Python 2to3 Transition
Recently I’ve upgraded one of our biggest projects from Python2.7 to Python3.6, and the process is quite smooth. It tooks me almost 2 days to complete all conversion needed, while other developers were still doing their dail jobs in the project.

Some key notes here:
1, Having a solid unit tests system is critical.
2to3did all the heavy works, but you need to know the stuffs to get all the shit done.
