title: removing [u''] in the django template
body: <p><br>
  I'm trying to load JSON into a Django template, and this goes well. But I get [] around it and 'u before it. I was wondering if there is something I could do against it. this is the code I use:</p>
  
  <pre><code>json_response = requests.get(endpoint + "appointments?user="+user+"&amp;access_token="+token+"&amp;start="+str(int(timestamp_start))+"&amp;end="+str(int(timestamp_end))+"&amp;valid=true").json()
  appointmentsVrijdag = json_response['response']['data']
  return render(request, template, {"appointmentsVrijdag": appointmentsVrijdag})
  </code></pre>
  
  <p>Then, to load it in the template I use the following code:</p>
  
  <pre><code>            {% for appointment in appointmentsVrijdag %}
              {% if appointment.cancelled != True %}
                  &lt;tr&gt;
                       &lt;td&gt;
                           {{ appointment.teachers }}
                           {{ appointment.subjects }}
                       &lt;/td&gt;
                  &lt;/tr&gt;
              {% endif %}
          {% endfor %}
  </code></pre>
  
  <p>I was hoping to get some help!</p>
