Cannon: Why Python 3 exists

Brett Cannon reminds the world why the Python developers decided to create Python 3 — and acknowledges that the transition could have been done better. "This point of avoiding bugs is a big deal that people forget. The simplification of the language and the removal of the implicitness of what a str object might represent makes code less bug-prone. The Zen of Python points out that 'explicit is better than implicit' for a reason: ambiguity and implicit knowledge that is not easily communicated code is easy to get wrong and leads to bugs. By forcing developers to explicitly separate out their binary data and textual data it leads to better code that has less of a chance to have a certain class of bug."
