Django template tags within a hyperlink

In my .html file, I have this code:

<ul>    {% for file in files %}<li><a href="{% static 'notebooks/<**Part that I want to reference dynamically**>' %}">{{ file }}</a></li>    {% endfor %}</ul>

In my views.py file:

def ipythonlist(request):    files = []     main_dir = os.path.abspath(os.path.join(os.path.dirname(__file__), 'static/'))    ipython_file_path = os.path.join(main_dir, 'notebooks/')    for file in os.listdir(ipython_file_path):        if file.endswith(".html"):            files.append(file)    return render(request, 'pages/ipythonlist.html', {'files': files})

And my url file:

url(r'^ipython/list', views.ipythonlist, name='ipythonlist')

So what I am trying to do is get a list of all the .html files (or any type of files for that matter, pdf, csv, etc.) within a directory in my static folder. Then I pass this data from the views into my html using template tags. I want to link to that corresponding file dynamically, but I am not sure how to do that.

I tried {% static 'notebooks/{{file}}' %}, but that just returned an error.

Not sure how to do this and would appreciate some help!

So an example of the link to a file would be {% static 'notebooks/chapter9.pdf' %}. Where chapter9, can be any name.
