Dictionary lookups in templates?

[JA]

Hi,

I am trying to perform a dictionary lookup within a template, and have
got stuck.  I pass a list( dirList ) and a dict ( thumbNames ) to
render_to_response. Within the template I process the list, and print
each occurence of dirList.  What I would like to do, is display an
entry of thumbNames based on the value of dirName.  Something like:

{% for dirName in dirList %}
    {{ dirName }} - {{ thumbNames.{{ dirName }} }}
{% endfor %}

Is there a way of implementing something like this?  I'd appreciate any
pointers.

Regards

J
