Python實現批量獲取文件夾內文件名并重命名

更新時間：2025年02月09日 09:10:31 作者：一晌小貪歡

這篇文章主要為大家詳細介紹了Python如何批量獲取文件夾內文件名及重命名文件,文中的示例代碼講解詳細,感興趣的小伙伴可以跟隨小編一起學習一下

1、背景介紹

有時候我們經常需要將批量的文件進行重命名，比如：

① 批量在文件名【前面】加上自定義字符
② 批量在文件名【后面】加上自定義字符
③ 批量在【替換】文件名中的字符
④ 批量去除空格
⑤ 結果可以選擇復制文件或者移動文件

2、庫的安裝

庫	用途	安裝
PyQt5	界面設計	pip install PyQt5 -i https://pypi.tuna.tsinghua.edu.cn/simple/
shutil	文件移動	內置庫無需安裝
os	文件移動	內置庫無需安裝

3、核心代碼

復制或移動

shutil.move(old_file, new_file)  # 移動文件
shutil.copy2(old_file, new_file)  # 復制文件
