threads

[Bart Nessux]

Could someone explain the concept of threads and how I might use them in 
Python? I was a math major, not a CS major (theory instead of practice). 
Most of my programming knowledge has grown out of system administration 
and shell scripting, not professional software development.

How could I make this script threaded, and why should I, how would it 
benefit me? The script already takes up 100% CPU resources, what would 
using threads gain for me:

#!/usr/bin/python	#change this to your Python's path

def cpu_test():
    x = 0
    while x < 999999999:
       x = x + 1
       print x
    cpu_test()
cpu_test()

If the above is not suitable for threading, please give me a short 
example of something that is.

Thanks!!!
