That's not a Linux problem. For the code to run in 

>> s='<news server>'

>> n=t.NNTP(s,119,'<usr>','<pw>')

you need to replace the '<...>' strings with a real news server, user, and 
password. If you use Gmane no password is required:

n = t.NNTP("news.gmane.org")

However, they use a different name for the "comp.lang.python" group, so you 
have to modify the command line accordingly:

$ python stats.py gmane.comp.python.general last 500
