Python glob.glob（dir）內存錯誤

Question

搜索包含數百萬個文件的文件夾時，我正在處理內存問題。 有誰知道如何克服這種情況？ 有什么方法可以限制glob搜索的文件嗎？ 因此可以分塊執行嗎？

Traceback (most recent call last):
  File "./lb2_lmanager", line 533, in <module>
   main(sys.argv[1:])
 File "./lb2_lmanager", line 318, in main
    matched = match_files(policy.directory, policy.file_patterns)
  File "./lb2_lmanager", line 32, in wrapper
    res = func(*args, **kwargs)
  File "./lb2_lmanager", line 380, in match_files
    listing = glob.glob(directory)
  File "/usr/lib/python2.6/glob.py", line 16, in glob
    return list(iglob(pathname))
  File "/usr/lib/python2.6/glob.py", line 43, in iglob
    yield os.path.join(dirname, name)
  File "/usr/lib/python2.6/posixpath.py", line 70, in join
   path += '/' + b

嘗試使用generators而不是lists 。
要了解什么發電機閱讀此

import glob
dir_list = glob.iglob(YOUR_DIRECTORY)
for file in dir_list:
    print file

將YOUR_DIRECTORY更改為您要列出的目錄。
