如何根据文本值的存在拆分JSON对象？

import json

def split_json_by_text(json_obj, text_value):
    new_json_obj = {}
    
    for key, value in json_obj.items():
        if isinstance(value, dict):
            sub_json_obj = split_json_by_text(value, text_value)
            if sub_json_obj:
                new_json_obj[key] = sub_json_obj
        elif isinstance(value, list):
            sub_json_list = []
            for item in value:
                if isinstance(item, dict):
                    sub_json_obj = split_json_by_text(item, text_value)
                    if sub_json_obj:
                        sub_json_list.append(sub_json_obj)
                elif isinstance(item, str) and item == text_value:
                    sub_json_list.append(item)
            if sub_json_list:
                new_json_obj[key] = sub_json_list
        elif isinstance(value, str) and value == text_value:
            new_json_obj[key] = value
    
    return new_json_obj

# 示例JSON对象
json_str = '''
{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York"
    },
    "hobbies": ["reading", "music", "sports"],
    "skills": {
        "programming": "Python",
        "database": "MySQL"
    }
}
'''

# 解析JSON字符串为字典
json_obj = json.loads(json_str)

# 根据文本值的存在拆分JSON对象
text_value = "Python"
new_json_obj = split_json_by_text(json_obj, text_value)

# 打印拆分后的新JSON对象
print(json.dumps(new_json_obj, indent=4))
