Conclusion
Overall, the changes outlined here have a high impact in terms of updates required to the interpreter, but shouldn't radically change the way in which you write your Python code. It's a matter of habit, such as using parentheses with print—or rather, print(). Once you have these changes under your belt, you're well on your way to being able to jump to the new platform. It maybe a bit startling at first, but it's a change that has been coming for some time. Don't panic; 2.x will live on for a long time to come. The transition will be slow, deliberate, pain-resistant, and even-keeled. Welcome to the dawn of the next generation!
