I didn't see a followup on this post, so I thought I would add my
ignorance to the discussion.
first, I don't think you can assign a variable name to a python
function using tal and then have tal 'call' the function.
second, I think what you do want is the get the results of calling
getQuote into the variable called 'num', and then use those results
I think tal variables can all be first class python objects. If not,
any standard python object works -- in other words, a list, tupple,
string, dictionary, etc. If you have your own object, it will need to
have an iterator method defined for it -- but then, I wouldn't know
how to make the new class known to zope.

acquisition will find many things. What does getQuote return though?
