Jinja2 and HTML Div tag

I have an html file which I am rendering with jinja2 in python, which has some div sections like

<div id="imdb">
{{imdb_output}}
</div>

Now even when the value of imdb_output variable is returned None from its function in python file, as expected HTML still displays the div section although with no content, but with its css!

But what do I need to do so that even the empty div section does not appear if imdb_output has no values to display?? Do I need to add some JS?

Please help!

Here is a screenshot of the problem:- https://i.sstatic.net/uIhzH.jpg

Just check if imdb_output is empty:

{% if imdb_output %}
  <div id="imdb">
    {{imdb_output}}
  </div>
{% endif %}

use this 

{% if imdb_output %}
    <div id="imdb">
        {{imdb_output}}
    </div>
{% endif %}

You should read jinja2 documentation for template designers
