如何返回多个forloop结果(Django)

results = []
for item1 in queryset1:
    for item2 in queryset2:
        # 处理逻辑
        result = {'item1': item1, 'item2': item2}
        results.append(result)

context = {'results': results}
return render(request, 'template.html', context)

{% for result in results %}
    <p>{{ result.item1 }}</p>
    <p>{{ result.item2 }}</p>
{% endfor %}

results = {}
for item1 in queryset1:
    results[item1] = []
    for item2 in queryset2:
        # 处理逻辑
        result = {'item1': item1, 'item2': item2}
        results[item1].append(result)

context = {'results': results}
return render(request, 'template.html', context)

{% for item1, item2_list in results.items %}
    <p>{{ item1 }}</p>
    {% for result in item2_list %}
        <p>{{ result.item2 }}</p>
    {% endfor %}
{% endfor %}
