  • Starting standard library reorganizations
  • Introducing function annotations
  • Introducing new syntax for exception handling

As we know from Chapter 1, Current Status of Python, Python 3 isn't backward-incompatible with Python 2. This is the main reason why it took so many years for the Python community to fully embrace it. That was a tough, albeit necessary, lesson for Python core developers and the Python community.

Fortunately, problems associated with the adoption of Python 3 didn't stop the process of language evolution. Since December 3, 2008 (the official release of Python 3.0), we've seen a stable inflow of new major Python updates. Every...
