Start up the Python prompt, and type 'import this'. Then see what happens.

Though these things are subjective as well, so yes, these things, the
Python idiomatic way (which itself is an evolving concept).

Zope 2 definitely doesn't always fit that shoe, though (with effort) it
is possible to write reasonably modern "Pythonic" code that still fits
within the Zope framework. Mostly the trick is not to use the framework
but to write plain Python code when you can get away with it. I think I
can do that, but it is the result of a lot of experience and an
experienced Python programmer new to Zope 2 will not know how to do it.
In Zope 3, a lot of effort was taken to allow the integration of
Pythonic code. Zope 3's codebase itself is also a lot more modern
Python, so could qualify as "Pythonic" as well. Unfortunately turn-offs
for Python developers new to Zope 3 are ZCML and the sheer magnitude of
the framework and the amount of new concepts involved. I believe
something like ZCML is necessary, but it being an XML glue language,
it's automatically not perceived as very Pythonic at first impression.
The magnitude of the framework and new concepts involved is, at least in
part, a problem for any large framework, not just Zope.
Note that Five is an attempt to bring some of the 'increased
Pythonicness' (the ability to "just write Python code" without worrying
about lots of Zope specific things) from Zope 3 to Zope 2.

Yes. "this is (not) Pythonic" is therefore of limited use in any
argument if the other guy doesn't agree, but quite important if the
other guy *does* agree. :)

Martijn; an interesting displacement of the 'j' there. :)
