I'd suggest "pythonic", rather than obvious, for that sentence. It's one of the ways the community reminds itself of the utility of consistent discipline.
It's perhaps worth noting that the next line of the Zen of Python is: "Although that way may not be obvious at first unless you're Dutch." (I.e. unless you're Guido.)
So it was a bit of a tongue in cheek statement from the very beginning. :D
Are there some exceptions? Sure.
