python - Peculiar error downloading keys/files from S3 bucket - [Errno 1] Operation not permitted -

-

i'm using python script files in s3 bucket. relevant code snippet follow:

        print ("downloading files...")         f in files:             cwd=os.getcwd()             fname=cwd+"/"             fname = fname+f.name             dir = os.path.dirname(fname)             if not os.path.exists(dir):                      print dir                     os.makedirs(dir)             try:                 f.get_contents_to_filename(fname)             except oserror,e:                 print e

when on bucket used store log files, error on folders in bucket. e.g. logs folder here:

downloading files... /private/tmp/test/logs [errno 1] operation not permitted: '/private/tmp/test/logs/

despite error, directories , files downloaded.

why happen? not happen on other buckets, except bucket log files other buckets sent to. or code? or permissions on bucket. has default permissions, nothing have changed.

taking @pavel_form's suggestion, figured out problem. trying write directory file. fixed code using block, checking if basename empty:

            if (not os.path.basename(fname)==""):                 try:                     f.get_contents_to_filename(fname)                 except oserror,e:                     print e
