验证Json对象中是否存在列表<String>的值​，并返回True或False

import json

def check_json_for_string_list(json_obj):
    if isinstance(json_obj, dict):
        for value in json_obj.values():
            if isinstance(value, list):
                if all(isinstance(item, str) for item in value):
                    return True
            elif isinstance(value, dict):
                if check_json_for_string_list(value):
                    return True
    elif isinstance(json_obj, list):
        for item in json_obj:
            if isinstance(item, dict):
                if check_json_for_string_list(item):
                    return True
    return False

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

# 解析Json字符串为对象
json_obj = json.loads(json_str)

# 验证Json对象中是否存在列表<String>的值
result = check_json_for_string_list(json_obj)
print(result)
