In Zope 2, you can use the function 'test' in a python expression in a 
page template.

   <p tal:content="python: test(
             somecondition, 'was true', 'was not true')" />

This is not present in the Zope 3 version. There is some debate as to 
whether it should be supported in Zope 3 or not.

There was some discussion of a variety of possible syntaxes for 
conditional expressions in TALES. I don't think there was any consensus.
It would be nice if it were easier to express simple conditionals in TALES.
