You context dictionary key is “latest_question_list”, and this is passed into 
your template.  Your python variable is named latest_ques, which the template 
is not aware of.

So you need to change your html temple or your context key.

 

Also, watch your case.  “question” and “Question” are two different variables.

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Polls</title>
</head>
<body>
{% if latest_question_list %}
    <ul>
    {% for question in latest_question_list %}
        <li><a href="/polls/{{ question.id }}/"><b>{{ question.question_text 
}}</b></a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No polls are available.</p>
{% endif %}

</body>
</html>
