如何从ID搜索txt文件中的具体数据

def search_data_by_id(file_path, target_id):
    try:
        with open(file_path, 'r') as file:
            for line in file:
                # 提取ID
                id = line.split(',')[0]  # 假设ID在每行数据的第一个字段，以逗号分隔
                if id == target_id:
                    # 提取具体数据
                    data = line.split(',')[1]  # 假设具体数据在每行数据的第二个字段，以逗号分隔
                    return data
    except FileNotFoundError:
        print("文件不存在")
    except Exception as e:
        print("发生错误：", str(e))

# 示例用法
file_path = "data.txt"  # txt文件路径
target_id = "12345"  # 目标ID
result = search_data_by_id(file_path, target_id)
if result:
    print("找到了目标数据：", result)
else:
    print("未找到目标数据")
