title: List comprehensions in Jinja
body: <p>I have two lists:</p>
  
  <ol>
  <li>strainInfo, which contains a dictionary element called 'replicateID'</li>
  <li>selectedStrainInfo, which contains a dictionary element called 'replicateID'</li>
  </ol>
  
  <p>I'm looking to check if the replicateID of each of my strains is in a list of selected strains, in python it would be something like this:</p>
  
  <pre><code>for strain in strainInfo:
      if strain.replicateID in [selectedStrain.replicateID for selectedStrain in selectedStrainInfo]
          print('This strain is selected')
  </code></pre>
  
  <p>I'm getting the correct functionality in django, but I'm wondering if there's a way to simplify using a list comprehension:</p>
  
  <pre><code>{% for row in strainInfo %}
      {% for selectedStrain in selectedStrainsInfo %}
         {% if row.replicateID == selectedStrain.replicateID %} 
             checked 
         {% endif %}
      {% endfor %}
  {% endfor %}
  </code></pre>
