title: 'if' statement in jinja2 template
body: <p>I'm trying to write an if statement in <a href="https://jinja.palletsprojects.com/en/2.11.x/" rel="noreferrer">jinja template</a>:</p>
  <pre><code>{% for key in data %}
      {% if key is 'priority' %}
          &lt;p&gt;('Priority: ' + str(data[key])&lt;/p&gt;
      {% endif %}
  {% endfor %}
  </code></pre>
  <p>the statement I'm trying to translate in Python is:</p>
  <pre><code>if key == priority:
      print(print('Priority: ' + str(data[key]))
  </code></pre>
  <p>This is the error i'm getting:</p>
  <blockquote>
  <p>TemplateSyntaxError: expected token 'name', got 'string'</p>
