[Zope-dev] Return anything but strings from a method??

[Chris McDonough]

Thomas,

An example external method:

def foo():
    return [1,2,3]

A DTML method that calls the external method (also named foo) that
references the foo method:

<dtml-in foo>
   <dtml-var sequence-item>
</dtml-in>

returns "1 2 3"

<dtml-var "foo()[0]">

returns "1"

Another python method:

def bar():
     return {'a':1, 'b':2, 'c':3}

DTML:

<dtml-var "bar()['a']">
 
returns "1"

A minor note: please try not to send HTML formatted mail to the list. 
Thanks!
