在python中将sql查询结果转换为JSON数组

我在Python中从SQLite获得的结果如下：

{"John", "Alice"}, {"John", "Bob"}, {"Jogn", "Cook"} ......

{
    "Teacher": "John",
    "Students": ["Alice", "Bob", "Cook" .....]
}

我想将结果转换为JSON格式，如下所示：

{"John", "Alice"}, {"John", "Bob"}, {"Jogn", "Cook"} ......

{
    "Teacher": "John",
    "Students": ["Alice", "Bob", "Cook" .....]
}

我使用GROUP_CONCAT记录所有学生的姓名和以下代码：

row_headers = [x[0] for x in cursor.description] #this will extract row headers
result = []
for res in cursor.fetchall():
    result.append(dict(zip(row_headers, res)))

我能够得到这个结果：

{
    "Teacher": "John",
    "Students": "Alice, Bob, Cook" 
}

如何将学生转换为数组格式？

您只需执行

result[“students”]=result[“students”]。拆分（“，”）
如果您的sqlite版本启用了扩展，那么在纯SQL中很容易做到：

SELECT json_object('Teacher', teacher,
                   'Students', json_group_array(student)) AS result
FROM ex
GROUP BY teacher;

不错！但是如果学生的名字中包含“，”怎么办？
