Question

在下面的代码中，我无法将重命名的文件保存在与/ Users / xxx / Documents / Dates原始文件相同的目录中

我正在寻求帮助来解释原因？

#! usr/bin/env python3
# renameDates.py - Renames filenames with America MM-DD-YYYY date format
# to European DD-MM-YYYY 

import shutil, os, re

#create a regex that matches files with the America date format. 
datePattern = re.compile(r'''^(.*?) # all text before the date
        ((0|1)?\d)-                 #one or two digits for the month
        ((0|1|2|3)?\d)-             #one or two digits for the day 
        ((19|20)\d\d)               #four digits for the year 
        (.*?)$                      #all text after the date 
        ''', re.VERBOSE)

for amerFilename in os.listdir('/Users/xxx/Documents/Dates'):
    mo = datePattern.search(amerFilename)
    if mo == None:
        continue

    beforePart = mo.group(1)
    monthPart = mo.group(2)
    dayPart = mo.group(4)
    yearPart = mo.group(6)
    afterPart = mo.group(8)
    euroFilename = beforePart + dayPart + '-' + monthPart + '-' + yearPart + afterPart
    absWorkingDir = os.path.abspath('./Dates')
    amerFilename = os.path.join(absWorkingDir, amerFilename)
    print('Renaming "%s" to :%s:...' % (amerFilename, euroFilename))
    shutil.move(amerFilename, euroFilename) #uncomment after testing

Answer 1

您在for语句中从特定目录（＆＃39; / Users / xxx / Documents / Dates＆＃39;）中提取amerFilename文件。但是，然后将它们移动到euroFilename，该文件名定义为文件名，但未在同一特定目录中定义。

如果您将最后一行更改为：

shutil.move(amerFilename, os.path.join('/Users/xxx/Documents/Dates', euroFilename))

......你得到你想要的东西吗？
