I'm trying to rename some files in a directory using Python. 我正在嘗試使用Python重命名目錄中的一些文件。

Say I have a file called CHEESE_CHEESE_TYPE.*** and want to remove CHEESE_ so my resulting filename would be CHEESE_TYPE 假設我有一個名爲CHEESE_CHEESE_TYPE.***的文件，並且想刪除CHEESE_因此我的結果文件CHEESE_TYPE

I'm trying to use the os.path.split but it's not working properly. 我正在嘗試使用os.path.split但它無法正常工作。 I have also considered using string manipulations, but have not been successful with that either. 我也考慮過使用字符串操作，但也沒有成功。

此命令將在當前目錄下的所有文件刪除初始 “CHEESE_”的字符串，用重命名 ：

$ renamer --find "/^CHEESE_/" *

This sort of stuff is perfectly fitted for IPython, which has shell integration. 這種東西非常適合IPython，它具有shell集成。

In [1] files = !ls
In [2] for f in files:
           newname = process_filename(f)
           mv $f $newname

Note: to store this in a script, use the .ipy extension, and prefix all shell commands with ! 注意：要將其存儲在腳本中，請使用.ipy擴展名，並在所有shell命令前加上! . 。

The following code should work. 以下代碼應該有效。 It takes every filename in the current directory, if the filename contains the pattern CHEESE_CHEESE_ then it is renamed. 它接受當前目錄中的每個文件名，如果文件名包含模式CHEESE_CHEESE_ ，則重命名。 If not nothing is done to the filename. 如果沒有對文件名做任何事情。

import os
for fileName in os.listdir("."):
    os.rename(fileName, fileName.replace("CHEESE_CHEESE_", "CHEESE_"))

Here is a more general solution: 這是一個更通用的解決方案：

This code can be used to remove any particular character or set of characters recursively from all filenames within a directory and replace them with any other character, set of characters or no character. 此代碼可用於從目錄中的所有文件名中遞歸刪除任何特定字符或字符集，並將其替換爲任何其他字符，字符集或無字符。

import os

paths = (os.path.join(root, filename)
        for root, _, filenames in os.walk('C:\FolderName')
        for filename in filenames)

for path in paths:
    # the '#' in the example below will be replaced by the '-' in the filenames in the directory
    newname = path.replace('#', '-')
    if newname != path:
        os.rename(path, newname)

Here's a script based on your newest comment. 這是基於您最新評論的腳本。

#!/usr/bin/env python
from os import rename, listdir

badprefix = "cheese_"
fnames = listdir('.')

for fname in fnames:
    if fname.startswith(badprefix*2):
        rename(fname, fname.replace(badprefix, '', 1))
