1、背景介绍
有时候我们经常需要将批量的文件进行重命名，比如：
- ① 批量在文件名【前面】加上 自定义字符
- ② 批量在文件名【后面】加上 自定义字符
- ③ 批量在【替换】文件名中的字符
- ④ 批量去除 空格
- ⑤ 结果可以选择复制文件 或者 移动 文件
2、库的安装
| 库 | 用途 | 安装 |
|---|---|---|
| PyQt5 | 界面设计 | pip install PyQt5 -i https://pypi.tuna.tsinghua.edu.cn/simple/ |
| shutil | 文件移动 | 内置库无需安装 |
| os | 文件移动 | 内置库无需安装 |
3、核心代码
复制 或 移动
shutil.move(old_file, new_file) # 移动文件 shutil.copy2(old_file, new_file) # 复制文件
