Python Tornado: nested templating

Is it possible to do some sort of eval in tornado templates?

Let me show an example of what I wish to do:

{% for c in columns %}
    <!-- cdata is a dictionary, and columns is a list -->
    <div class="cell"> {{ cdata[ {{ c }} ] }} </div>
{% end %}

e.g. I want to evaluate the current value in columns, and use it as a key to search in the cdata dictionary.

How do I do that?

Thanks

Expressions in Tornado templates cannot be nested, but they're just python expressions, which gives you the flexibility to do what you want. This includes calling the python eval if that's what you need, but it looks like in this case you simply need {{ cdata[c] }}.
