[Zope] Re: TAL: test() or condition Howto? solved!!!

Hi Evan, BINGO, that's it --- just when I was getting familar with the idea of adopting one more cute python-thingy your idea came along. I knew it should be possible :), but the idea of putting the condition in the define-slot is just exellent and makes it. My zen of python has increased one step further, thanks a lot. May this one should be mentioned at zope-labs. (you get a 5 star-rating from my side) -- thanks again, Elena

Thanks to the way Python's "and" works, you can do the following:

<td tal:define="x python:myImportantCondition and myExpensiveMethod()" tal:content="python:x or default">myDefaultString</td>
