如何通过遍历python嵌套字典来创建html表

def create_html_table(data):
    html_code = "<table>"
    
    for key1, value1 in data.items():
        html_code += "<tr>"
        html_code += "<th>{}</th>".format(key1)
        
        for key2, value2 in value1.items():
            html_code += "<td>{}</td>".format(value2)
        
        html_code += "</tr>"
    
    html_code += "</table>"
    
    return html_code

# 示例数据
data = {
    "姓名": {
        "年龄": "25",
        "性别": "男"
    },
    "地址": {
        "城市": "北京",
        "街道": "朝阳区"
    }
}

# 调用函数生成HTML表格代码
html_table = create_html_table(data)

# 打印生成的HTML表格代码
print(html_table)
