Scarf_song_titles.py
This prints a list of songs from the iTunes db based on search terms
that you place inside the program for each run. Crude, I know...
Works fine, though.
Requires python3.1

# Q:: Isn"t this cheating?
# A:: Not if everybody was using it.
# This runs on python3.1 on any platform you can imagine.
# Tested on a Mac (v. 10.6.3)
# the paths defined in this section might be different on a PC or Gnu/Linux
# To run this on a Mac, Gnu/Linux or PC:
# 0) uncomment the two lines below the WARNING.
# this gives the program PERMISSION to read your db and write a datafile
# 1) download python3.1
# 2) paste this program into a file called scarf_song_titles.py
# 3) fire up IDLE at Applications/Python 3.1/IDLE
# 4) File/Open scarf_song_titles.py
# 5) put your search criteria into two spots indicated
# 5) hit F5 to Run
# 6) click in the IDLE and goto step 5
# IMPORTANT:
# USE AT YOUR OWN RISK! The author does not warrent the reliability of this program.
# IFF you will allow this program to read your iTunes_Music_Library.xml
# fix the path and uncomment the next line...
#XMLfile = "/Users/paul/Music/iTunes/*.xml"
# I have to create an ASCII-only version of that file to avoid a program error.
# IFF you will allow this program to create such a file
# fix the path and uncomment the next line...
#datafile = "/Users/paul/song_title_game_data.xml"
# remove this file after you have installed some new tunes

This is an error because the write method can only output a string.
Strings in Python are not strictly 7-bit characters, but 8-bit bytes.
So you can use the struct module to convert Python data into binary
strings, which can then be written to the file.
>>> import struct
>>> binfile = open('bin.dat', 'wb')
>>> for num in range(50):
... data = struct.pack('i', num)
... binfile.write(data)
...
>>> binfile = open('bin.dat', 'rb')
>>> intsize = struct.calcsize('i')
>>> while 1:
>>> data = binfile.read(intsize)
... if data == '':
... break
... num = struct.unpack('i', data)
... print num
