The problem with trying to translate DTML to Python is that <dtml-var
xxx> incorporates a lot of magical behaviour. Apart from rendering the
object (calling it if it is callable), as implied by the ()-or-no-()
above, the name 'xxx' could be found in many places. Here's a sampling
of ways to access an object 'xxx' in a Script:
1. From the target of the Script, or its context:
context.xxx
getattr(context, 'xxx')
2. From the Script's container, regardless of context:
container.xxx
getattr(container, 'xxx')
3. From a submitted form, cookies, URL query, or REQUEST.set() call:
context.REQUEST['xxx']
context.REQUEST.form['xxx']
context.REQUEST.cookies['xxx']
context.REQUEST.other['xxx']
