Hello, Today i wrote a little (internal) python script for manipulating lists. I first tried in pure python using reduce() and map() and it worked just fine. So, i copied my code to the zope python-script and tried it there. It said something like 'reduce not known'. When i changed my code to work without reduce() it worked fine again. But i didn't need to remove map(). Is there an explanation? br, stephan -- Mag.
