删除JSON文件中的字符串的值

import json

def delete_json_value(json_file, target_string):
    # 读取JSON文件并解析为对象
    with open(json_file, 'r') as file:
        json_data = json.load(file)

    # 递归遍历JSON对象，删除目标字符串的值
    def delete_value(obj):
        if isinstance(obj, dict):
            for key, value in obj.items():
                if value == target_string:
                    obj[key] = None  # 或者使用 del obj[key] 删除键值对
                else:
                    delete_value(value)
        elif isinstance(obj, list):
            for item in obj:
                delete_value(item)

    delete_value(json_data)

    # 将修改后的JSON对象转换为字符串并写回文件
    with open(json_file, 'w') as file:
        json.dump(json_data, file)

# 示例用法
delete_json_value('data.json', 'target_string')
