如何在python中更改文件夹名称? [英] How to change folder names in python?

问题描述

我有多个文件夹，每个文件夹都有一个人的名字，名字在前，姓氏在后.我想更改文件夹名称，以便姓氏后跟逗号，然后是名字.

I have multiple folders each with the name of a person, with the first name(s) first and the surname last. I want to change the folder names so that the surname is first followed by a comma and then the first name(s) follow.

例如，在文件夹 Test 中，我有:

As an example, in the folder Test, i have:

C:/Test/John Smith
C:/Test/Fred Jones
C:/Test/Ben Jack Martin

我想做这个:

C:/Test/Smith, John
C:/Test/Jones, Fred
C:/Test/Martin, Ben Jack

我用 os.rename 尝试了一些东西，但我似乎无法让它在不同的名字长度下工作，而且我不知道如何在姓氏中插入逗号.

I tried some things with os.rename but i couldn't seem to make it work with the varying name length, and i wasn't sure how to insert the comma into the surname.

另外，一些文件夹名称已经是正确的格式，所以我需要在重命名时跳过这些文件夹.我认为你可以通过添加一个 if 来做到这一点，这样如果文件夹名称包含逗号，它就会继续.

Also, some of the folder names are already in the correct form, so i need to skip these folders during the renaming. I think you can do this by just adding an if, so that if the folder name contains a comma it will continue.

否则，姓氏将始终是文件夹名称中的最后一个字.

Otherwise, the surname will always be the last word in the folder name.

感谢您提供的任何帮助.

Thanks for any help you can provide.

推荐答案

您可以使用 os.listdir 和 os.path> 功能:

You can write it out fairly straight-forward, using os.listdir and the os.path functions:

import os
basedir = 'C:/Test'
for fn in os.listdir(basedir):
  if not os.path.isdir(os.path.join(basedir, fn)):
    continue # Not a directory
  if ',' in fn:
    continue # Already in the correct form
  if ' ' not in fn:
    continue # Invalid format
  firstname,_,surname = fn.rpartition(' ')
  os.rename(os.path.join(basedir, fn),
            os.path.join(basedir, surname + ', ' + firstname))
