用python替换Filename字符

Question

我有一些代码在文件名加载的末尾添加了"_manual"这个词.我需要更改脚本,以便删除文件名(ES)的最后两个字母,然后用_ES_Manual替换它,例如: AC-5400ES.txt - > AC-5400_ES_manual.txt

我如何将该功能合并到此代码中？

folder = r"C:/Documents and Settings/DuffA/Bureaublad/test"
import os # glob is unnecessary
for root, dirs, filenames in os.walk(folder):
    for filename in filenames:
        fullpath = os.path.join(root, filename)
        filename_split = os.path.splitext(fullpath) # filename and extensionname (extension in [1])
        filename_zero, fileext = filename_split
        print fullpath, filename_zero + "_manual" + fileext
        os.rename(fullpath, filename_zero + "_manual" + fileext)

Answer 1

试试这个:

import os
pathiter = (os.path.join(root, filename)
    for root, _, filenames in os.walk(folder)
    for filename in filenames
)
for path in pathiter:
    newname =  path.replace('ES.txt', '_ES_manual.txt')
    if newname != path:
        os.rename(path,newname)

有关hughdbrown答案的更一般化的看法.此代码可用于删除任何特定字符或字符集.

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)
