Don't forget to write test cases. If you have a series of addresses, and confirm they are parsed correctly, you are in a good position to refine the pattern. You will instantly know if a change in pattern has broken another pattern.
The reason I'm saying this, is because I think your pattern is incomplete. I suggest you add a test case for the following street address: 221B Baker Street That is a real address in London (only Sherlock Holmes) was fiction. I know it, because I actually visited the location. Can you address matching pattern handle that? Just don't break other address recognition test cases while fixing things. -- http://mail.python.org/mailman/listinfo/python-list
