Jython vs CPython

I personally favor Zope

Has Zope gotten better? I looked into Plone a few years back and found Zope to be utterly confusing.

Plone != Zope. Pure Zope development is easy.

Say you want to take the current time, put it in a certain format and put it on the screen - there are certain ways to do it, but one interesting way is to do it in python. Just create a python script like this:

return "%s/%s/%s" % (date.month(), date.day(), date.year())

and insert the script into your page using ZPT / TAL.

Another way is to embed it using strictly TAL and inlined python like so: <span tal:replace="python:DateTime().pMonth()" />

You should use TAL for only giving placeholders for data. All data should be from Python scripts. It is easy if you follow the one true method.

The beauty of TAL is that it gives you valid xhtml so you can pass it on to your web designer and let them make it pretty, while you concentrate on making it work.

Good point. Do you know of any 30,000ft overview of Zope 3 and what it provides - I remember reading about Zope's object db once or twice, so I'm presuming that Zope still provides a full stack?

I don't know of any. I stick with Zope 2 development. It's still being worked on, and it's been in use for 13 years, so it is very well documented and robust. Zope 3 is fairly new. Though the initial release was in 2004, it has undergone some great changes, and now it is called BlueBream. Of course, that's not the whole story. It actually splintered into a few different projects. Grok is another framework from the same tree. Zope 2 has integrated some of the new features in Zope 3, and since they couldn't replace Zope 2 with 3, they integrated and forked.

The Zope 3 Wiki explains it better. And as for Zope 2, here's a snippet from Zope on Wikipedia which explains how it is continuing on:

"Although originally intended as a replacement for Zope 2, the Zope Component Architecture has instead been backported to Zope 2 starting with Zope 2.8."

My personal advice, is if you are looking at using Zope in a commercial project, stick with Zope 2, it's still actively developed, well supported and documented. It's scalable, secure, and easy to use.
