[Zope] calling an Python builtin function

Hi Zopistas, it's a pain looking to variables defined in a form such as checkboxes that can be a string if one is selected or a sequence if many are. to solve this problem i'd like to do something like: <dtml-let checkbox="list(checkbox)"> ... ... </dtml-let> That is, calling the list function of Python on checkbox. But that doesn't work, neither <dtml-let checkbox="_.list(checkbox)"> Beside of this, is there a way to test if foo is a string or a sequence or whatever ?? Thanks. -- ______________________________________________________ Felipe Alvarez Harnecker. QlSoftware.
