Not sure if this is related, but one thing I found which bit me recently is that prior to Python 2.5, pprint did not sort dict keys in the output. That means that a test like this: >>> pprint(foo) {'omega': 1, 'alpha': 2} will pass on 2.4 and fail on 2.5/2.6; to fix it for 2.5/2.6 you do: >>> pprint(foo) {'alpha': 2, 'omega': 1} but now it fails on 2.4. The only way I could find it make it work reliably was to not rely on dicts at all, but do: >>> pprint(sorted(foo.items()) [('alpha', 2), ('omega', 1)] Which works the same on both. I don't know if the zope.doctest pprint function was meant to fix this, but maybe it did? Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.
