Further, that's omitting a very important modifier from the koan.
Even without the parenthetical, the koan reads:
There should be one obvious way to do it.
So yes, there can certainly be multiple ways to do it. But it's very
important that there be one *obvious* way.
In other words: Don't present the user with a multitude of options with
no *obvious* choice for those who don't care (yet) to learn about the
choice. Make one of them *obvious* so that's the usually-correct choice.

And the Pythonic approach is to make an *obvious* way to do it. As you
say, ‘print’ is that one obvious way for emitting simple text output.
