Question

I have the following script:

import os
import stat

curDir = os.getcwd()+'/test'

for (paths, dirs, files) in os.walk(curDir):
        for f in files:
            if os.stat(f)[stat.ST_SIZE]>0:
                print f

and the folder test/:

test_folder:
    --test.wav
a.exe
t1
t2
rain.wav

when i run this script with geany it gives the following error:

Traceback (most recent call last):
  File "new_folder_deleter.py", line 8, in <module>
   if os.stat(f)[stat.ST_SIZE]>0:
   OSError: [Errno2] No such file or directory: 'a.exe'

but when I run it with IDLE:
it just prints test.wav in subfolder test_folder

Can anyone explain why it is so and how I can fix it?
P.S:
My aim is to browse all files and delete files with specified sizes.

Answer 1

You need to specify a full path for os.stat, unless the file is in the current working directory. The simplest way to fix this is to change the WD before trying to access the files:

curDir = os.getcwd()+'/test'
os.chdir(curDir)

A more general solution is to pass the full path to os.stat:

if os.stat(os.path.join(paths, f))[stat.ST_SIZE]>0:
  print f

I am not quite sure why IDLE does not produce an error here, though.
