如何从django模板的上下文中检索列表

from django.shortcuts import render

def my_view(request):
    my_list = ['item1', 'item2', 'item3']
    context = {'my_list': my_list}
    return render(request, 'my_template.html', context)

{% for item in my_list %}
    <p>{{ item }}</p>
{% endfor %}

{% if my_list|length > 0 %}
    <p>The list is not empty.</p>
{% else %}
    <p>The list is empty.</p>
{% endif %}
