Displaying a checkbox/list from database back onto a Django form

[NealWalters]

Template/Form looks like this:
English:<input type="checkbox" name="language" value="English" /><br/>
Spanish:<input type="checkbox" name="language" value="Spanish" /><br/>
Portuguese: <input type="checkbox" name="language" value="Portuguese" /
>

Database model defines column:
   languages           = db.StringListProperty()   #stores multiple
languages

I stored data into Google/BigTable like this:
   session.languages          = self.request.get_all('language')

That part works fine.

Now - I have the data stored, and I want to display it back on the
same form (the form is spread across 5 pages, and the user can move
backward and forward between the 5 pages).  I have stored the data in
a "Session" table and using Session objects to tie it together.

The list of languages might contain for example: English, Spanish,
French.
The form needs to set the checkboxes as "checked" if the appropriate
language is in my list, something like this:

    <img src="http://3wcloud.com/images/flags/english.jpg";>
&nbsp;&nbsp;
    <input type="checkbox" name="language" value="English" />&nbsp;
        {% ifequal Session.languages 'English' %}
        checked
        {% endifequal %}
        >English<br />

In the above, the keyword "ifequal" will do the job.

Is there some keyword like "iflistcontains"?    Do I have to do a
forloop and test myself?

I also tried this with no success:

        {% if session.languages['English'] %}
        checked
        {% endif %}

which gives this error:
    raise TemplateSyntaxError, "Could not parse the remainder: %s" %
token[upto:]
TemplateSyntaxError: Could not parse the remainder: ['English']

I guess this doesn't make sense because I have a list, not a
dictionary, of which "English" could just be one potential value.

Please - what will work for this scenario?
Thanks,
Neal Walters
