Next steps

- [Narrator] I hope that you've decided it's time…to migrate your codebase from Python 2 to Python 3.…I've shown almost all the changes that need to be made…and I hope I've also provided some assurance…that most of your code will not have to change dramatically.…I see three measurable benefits from using Python 3.…First, and most importantly,…Python 3 is a lot faster than Python 2.…In the early days of Python 3.5,…I collected the what's new documents…and counted almost 40 different places…where performance has been improved.…

Python 3.6 adds even more improvements to this list.…Second, Python 3 is bigger, it adds at least…a dozen new packages to the standard library.…New packages like enum, pathlib…and statistics are extremely helpful.…Third, Python 3 is internally simpler.…This means that it removes…some quirky behaviors of Python 2.…As one example, the complete separation…of Unicode text from sequences of bytes…can help prevent bugs from arising.…

There are two potential benefits to doing a migration.…One is the opportunity to improve code quality.…
