One of the early principles of python was there is one idiomatic python way of doing it. Usefully, this enforced a world-wide code style guide, making it easy to read python code. 2.7 and 3.x essentially forked the language, enabling different idiomatic ways to do the same thing which reduced this particular advantage of python. I'm looking forward to seeing the community merge up again.
