func.__test__ = False

What's the simplest possible buildout.cfg to install Zope 2? | 1,120,758 | <p>I know that the reccomended way to install Zope is with Buildout, but I can't seem to find a simple buildout.cfg to install a minimal Zope 2 environment. There are lots to install Plone and other things.</p>
<p>I've tried:</p>

Which is better in python, del or delattr? | 1,120,927 | <p>This may be silly, but its been nagging the back of my brain for a while. </p>

I'd only use the second one if you don't know the name of the attribute that you're deleting ahead of time.</p>
