Here's a code snippet I use:

<dtml-comment>
  oids   - If only one entry is checked, this is a string containing the
           value attribute, otherwise it's a list of value strings
  arrgs  - ARRGS!
  rowids - List of value strings to work with
</dtml-comment>
<dtml-let arrgs="REQUEST.get('oids',[])"
          rowids="[]">
  <dtml-try>
    <dtml-call "rowids.extend(arrgs)">
  <dtml-except TypeError>
    <dtml-call "rowids.append(arrgs)">
  </dtml-try>

[...]

</dtml-let>


The code relies on the fact that Python's LIST.extend() method
requires a list argument.
