Having examined your script, I'm not entirely sure what your input 
source is, so I'm assuming it's an mbox file of the archives from 
python-list, e.g. as appears on this page

http://mail.python.org/pipermail/python-list/

or at this URL

http://mail.python.org/pipermail/python-list/2005-November.txt

Those messages are the email versions, so all of the NNTP headers, e.g. 
NNTP-Posting-Host, will have been dropped. You will need these in order 
to get the geographic location of posts that have been made through NNTP.

In order to be able to get those headers, you need somehow to get the 
NNTP originals of messages that originated on UseNet. You can see an 
example of the format, i.e. your message to which I am replying, at this URL

http://groups.google.com/group/comp.lang.python/msg/56e3baabcd4498f2?dmode=source

The NNTP-Posting-Host for that message is '194.109.207.14', which 
reverses to 'bag.python.org', which is presumably the machine that 
gatewayed the message from python-list onto comp.lang.python.

So there are a couple of different approaches

1. Get an archive of the UseNet postings to comp.lang.python (anybody 
know where?)
  A: messages sent through email will have the NNTP-Posting-Host as
    a machine at python.org, so fall back to your original algorithm for
    those messages
  B: messages sent through UseNet, or a web gateway to same, will have an
    NNTP-Posting-Host elsewhere than python.org, so do your geo-lookup
    on that IP address.

2. Get the python-list archive
  A: Figure out which messages came through the python.org NNTP gateway
    (not sure offhand if this is possible). Automate a query to Google
    groups to find the NNTP-Posting-Host (using a URL like the one
    above). Requires being able to map the python-list message-id to the
    google groups message-id. Do your geo-lookup on that
    NNTP-Posting-Host value
  B: Use your original algorithm for messages sent through email.

2A message-id lookup should be achievable through the advanced google 
groups search, at this URL

http://groups.google.com/advanced_search?q=&

See the "Lookup the message with message ID" at the bottom.

Sorry I don't have time to supply code for any of this. Perhaps some one 
can add more details, or better still some code?
