如何在python中使用docxtpl jinja2标记的嵌套字典列表

from docxtpl import DocxTemplate

# 嵌套字典列表示例
data = [
    {
        'name': 'Alice',
        'scores': {'math': 90, 'science': 85},
        'courses': ['Math', 'Science']
    },
    {
        'name': 'Bob',
        'scores': {'math': 88, 'science': 92},
        'courses': ['Math', 'History']
    }
]

# 加载模板文档
doc = DocxTemplate('template.docx')

# 渲染模板
context = {'students': data}
doc.render(context)

# 保存结果
doc.save('output.docx')

{% for student in students %}
    <p>Name: {{ student.name }}</p>
    <ul>
        {% for subject, score in student.scores.items() %}
            <li>{{ subject }}: {{ score }}</li>
        {% endfor %}
    </ul>
    <p>Courses:</p>
    <ul>
        {% for course in student.courses %}
            <li>{{ course }}</li>
        {% endfor %}
    </ul>
{% endfor %}

<p>Name: {{ student.name | default('Unknown') }}</p>

for student in data:
    student.setdefault('name', 'Unknown')
    # ... 其他字段的默认值设置
