[Zope] dynamic format strings (was: using let and fmt)

[Matt Gregory]

I'm pretty knew to python, so I was looking at the problem from a strictly
dtml perspective.  Your solution will work nicely...

Specifically, I'm changing the links in a bunch of JavaScript arrays based
on a get method parameter defining the portlet retrieving the JavaScript.
There are possibly 8 portlets retrieving the JavaScript, so the links change
for each portlet.  For that reason I wanted to be able to dynamically format
the string resulting from the portlet name and get method parameters.
