代码按指定文件名存储数据，这样的缺点就是每一个输出文件都会覆盖前面生成的文件。
将文件名改成当前日期加时间，这样就不会重复了：

import os from datetime import datetime   # 生成时间戳（格式示例：2023-10-05_15-30-45） timestamp = datetime.now().strftime("%Y-%m-%d_%H-%M-%S")   # 动态生成带时间戳的文件名 output_path = os.path.join(output_dir, f'合并结果_{timestamp}.pdf')

其实重不重名根本不重要了，如果这个文件你需要重新生成，最好的办法就是直接覆盖，加了时间戳，大多数人根本分不太清哪个是哪个，程序需要二次转换就说明前一次生成的文件是不符合自己要求的

感谢楼主的分享，感谢感谢，学到了

我也搞了一个，想做成支持命令行模式，支持右键调用一键操作。但测试总是不理想，老哥这个能增加吗
