Python批量文件重命名工具：命名策略与实现-优快云博客

本文链接：https://blog.youkuaiyun.com/a494665/article/details/135042048

效果图：

点击更多命名方式后，可以基于一般的两种命名方法进行格式化：

我原先还想添加配置保存功能和命名失败后撤回功能的，但后来发现实现起来不仅有一定难度，而且可能对命名的性能造成一定影响。

我注意看了一下别人有些命名程序支持替换掉原命名中存在的某个字啥的，但感觉这种需求确实太特殊了，故没有添加这种功能。

为了使用方便还用nuikta打包成了exe程序，试了一下打包成多文件有点大不知道为什么...

fuc* you 想上传个exe也上传不了，只能说这"C*dn"真是rubbish 啊，反正你也不审核是吧哈哈哈，rubbish editor
