[ { "branch_id": 5, "branch_name": "分院2", "major_id": 3, "major_name": "专业2", "class_id": 5, "class_name": "班级2", "student_id": 11, "name": "xs1" }, { "branch_id": 5, "branch_name": "分院2", "major_id": 3, "major_name": "专业2", "class_id": 5, "class_name": "班级2", "student_id": 10, "name": "xs3" }, { "branch_id": 5, "branch_name": "分院2", "major_id": 3, "major_name": "专业2", "class_id": 5, "class_name": "班级2", "student_id": 9, "name": "bj2xs3" }, { "branch_id": 5, "branch_name": "分院2", "major_id": 3, "major_name": "专业2", "class_id": 5, "class_name": "班级2", "student_id": 8, "name": "bj2xs2" } ]

这是一个 JSON 格式的数据，它表示了一个班级的学生信息列表。如果你需要对这些数据进行处理，例如按照学生编号升序排序，可以使用以下 Python 代码：

import json

data = [
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 11,
        "name": "xs1"
    },
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 10,
        "name": "xs3"
    },
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 9,
        "name": "bj2xs3"
    },
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 8,
        "name": "bj2xs2"
    }
]

sorted_data = sorted(data, key=lambda x: x['student_id'])

print(json.dumps(sorted_data, indent=4, ensure_ascii=False))

运行结果如下：

[
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 8,
        "name": "bj2xs2"
    },
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 9,
        "name": "bj2xs3"
    },
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 10,
        "name": "xs3"
    },
    {
        "branch_id": 5,
        "branch_name": "分院2",
        "major_id": 3,
        "major_name": "专业2",
        "class_id": 5,
        "class_name": "班级2",
        "student_id": 11,
        "name": "xs1"
    }
]

以上代码使用了 Python 的 `sorted` 函数和 lambda 表达式对列表进行排序，然后使用 `json.dumps` 函数将结果转换为 JSON 格式的字符串并输出。
