Using python to examine your iTunes library

I recently noticed a bunch of music files were missing from my iTunes music library. Here's a simple python program I write to find which ones were missing... (iTunes tells you, but in a modal dialogue window so you can't look at the list and check your library at the same time)

import plistlib
import urllib

filename = "/Users/matt/Music/iTunes/iTunes Music Library.xml"


def check_file(dict):
 location = dict['Location']
 
 try:
  
  # try the url
  u = urllib.urlopen(location)
  
  # close it
  u.close()
  
  # if we get here, it was ok
  ok = True
  
 except:
  ok = False
 
 if (not ok):
  print "file not found: " + location


print "Reading iTunes xml file..."
x = plistlib.readPlist(filename)

tracks = x['Tracks']

for key in tracks.iterkeys():
 check_file(tracks[key])
