Python递归查找文件并移动到一个目标目录
该脚本应递归地遍历 rootpath 目录并查找所有具有 *.mp4 扩展名的文件。打印具有目录结构的文件列表。然后将文件移动到 destDir 目录。我遇到的问题是尝试将文件移动到新目录时。只有 rootPath 目录中的文件才会移动到新目标。 rootPath下子目录中的文件导致错误：
/Volumes/VoigtKampff/Temp/TEST/level01_test.mp4
/Volumes/VoigtKampff/Temp/TEST/Destination/2levelstest02.mp4
Traceback (most recent call last):
File "/Volumes/HomeFolders/idmo04/Desktop/ScriptsLibrary/Python/recursive_find.py", line 14, in <module>
shutil.move(root+filename, destDir+'/'+filename)
File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/shutil.py", line 281, in move
copy2(src, real_dst)
File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/shutil.py", line 110, in copy2
copyfile(src, dst)
File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/shutil.py", line 65, in copyfile
with open(src, 'rb') as fsrc:
IOError: [Errno 2] No such file or directory: '/Volumes/VoigtKampff/Temp/TEST/Destination2levelstest02.mp4'
import fnmatch
import os
import shutil
rootPath = '/Volumes/VoigtKampff/Temp/TEST/'
destDir = '/Volumes/VoigtKampff/Temp/TEST2/'
matches = []
for root, dirnames, filenames in os.walk(rootPath):
for filename in fnmatch.filter(filenames, '*.mp4'):
matches.append(os.path.join(root, filename))
print(os.path.join(root, filename))
shutil.move(root+filename, destDir+'/'+filename)
The script should recursively go through the rootpath directory and find all files with *.mp4 extension. Print the list of files with the directory structure. Then move the files to the destDir directory. The problem I run into is when trying to move the files to the new directory. Only files in the rootPath directory will be moved to the new destination. Files in subdirectories under rootPath causes errors:
/Volumes/VoigtKampff/Temp/TEST/level01_test.mp4
/Volumes/VoigtKampff/Temp/TEST/Destination/2levelstest02.mp4

############## here is the script
import fnmatch
import os
import shutil
rootPath = '/Volumes/VoigtKampff/Temp/TEST/'
destDir = '/Volumes/VoigtKampff/Temp/TEST2/'
matches = []
for root, dirnames, filenames in os.walk(rootPath):
for filename in fnmatch.filter(filenames, '*.mp4'):
matches.append(os.path.join(root, filename))
print(os.path.join(root, filename))
shutil.move(root+filename, destDir+'/'+filename)

恭喜！您已经找到了
os.path.join()。您甚至可以在print调用中使用它。因此，您只需将其与move()一起使用即可：（但请注意不要覆盖
destDir中的任何内容。）Congratulations! You have already found
os.path.join(). You even use it, on yourprintcall. So you only have to use it withmove():(But take care not to overwrite anything in
destDir.)将最后一行中的
root + filename更改为os.path.join(root, filename)（如前面两行所示）？Change the
root + filenamein the last line toos.path.join(root, filename)(as seen two lines earlier)?
