如何在django中将包含列表的字典中的值显示为值

def my_view(request):
    my_dict = {
        'key1': 'value1',
        'key2': ['value2', 'value3', 'value4'],
        'key3': 'value5',
    }
    return render(request, 'my_template.html', {'my_dict': my_dict})

{% for key, value in my_dict.items %}
    <p>{{ key }}: 
        {% if value|length > 1 %}
            <ul>
                {% for item in value %}
                    <li>{{ item }}</li>
                {% endfor %}
            </ul>
        {% else %}
            {{ value }}
        {% endif %}
    </p>
{% endfor %}
