如何将包含'_‘的JSON字段拆分成子对象？

import json

def split_json_fields(json_data):
    data = json.loads(json_data)
    for key in list(data.keys()):
        if '_' in key:
            parent, child = key.split('_', 1)
            if parent not in data:
                data[parent] = {}
            data[parent][child] = data[key]
            del data[key]
    return json.dumps(data)

# 示例用法
json_data = '{"parent_child": "value", "other_field": "value"}'
split_data = split_json_fields(json_data)
print(split_data)
