Question

Python 2.5.1

http://www.cgsecurity.org/wiki/After_Using_PhotoRec

I’ve just run PhotoRec and the code given as a way to sort file types into their own folder is coming back with this error. Any suggestions on how to alter? Thanks :

[EDIT2: Two points:

1. This question was voted down because it was a ‘usage’ of code, somehow not a programming question. Does it qualify as a coding question? I argue yes.

2. I’ve gone back and edited the page where the code came from to clarify the need for parameters for the benefit of others.]

   gyaresu$ python recovery.py Traceback (most recent call last): File ‘recovery.py’, line 8, in source = sys.argv[1] IndexError: list index out of range

Script:

#!/usr/bin/env python import os import os.path import shutil import string import sys  source = sys.argv[1] destination = sys.argv[2]  while os.path.exists(source) != True:     source = raw_input('Enter a valid source directory\n') while os.path.exists(destination) != True:     destination = raw_input('Enter a valid destination directory\n')  for root, dirs, files in os.walk(source, topdown=False):     for file in files:         extension = string.upper(os.path.splitext(file)[1][1:])         destinationPath = os.path.join(destination,extension)          if os.path.exists(destinationPath) != True:             os.mkdir(destinationPath)         if os.path.exists(os.path.join(destinationPath,file)):             print 'WARNING: this file was not copied :' + os.path.join(root,file)         else:             shutil.copy2(os.path.join(root,file), destinationPath) 

Answer 1

It simply means that the program is expecting two command line arguments: source and destination. If you wish to use the same code in another function, replace sys.argv[1] and [2] with your own variables.
