I love the changes to the language to remove the warts and to improve consistency across the language. Python thrives on consistency and always having exactly one obvious, readable way to do something. I welcome the simplified integer math, print function, unicode string unification, and other changes.

However, the biggest change, potentially, is function annotation. Function annotation brings the possibility of an extra level of documentation in code, of static-style type-checking which can easily be turned off in production, and of a standardized design by contract programming style.

Hopefully, we will have even bigger, easier to understand Python programs!
