Just off the top of my head (untested!) the following sort of thing should
work:

def AnExtMeth():
    return {1: 'one', 2: 'two', 3: 'three'}

<dtml-let dict="AnExtMeth()">
    <dtml-in expr="dict.items()">
&dtml-sequence-key; &dtml-sequence-item;
    </dtml-in>
1: <dtml-var expr="dict[1]">
</dtml-let>

or <dtml-call expr="REQUEST.set('dict', AnExtMeth())"> to make the
dictionary generally available.
