No, Java looks like the famous quotation about the nail and the horse from:

So which rule take precedents here? Namespace is obviously not flat, at least it's more nested than one without namespace.

That's the problem I have with people praising Zen of Python as if it means anything. It's like a bible you just pick the verse you like to justify your action even if it might conflict with other rules. Then you praise the whole thing for being so wise.

It means a lot: good python code follows it. However, yes, some of the verses conflict, because it turns out that good advice sometimes contradicts itself. All I can say is don't go too far in either direction.

Much of the point of the Zen of Python is that it's self-contradictory.

Balanced, you must be.
