You need to use double underscores. In Python, special method names are 
wrapped in double underscores. And you need a colon at the end of the line 
(maybe it was included in your code; I received a garbled message).

         def __init__(self, Hs, Town, Zip):

The interpreter did not recognise your "__init__" as a valid constructor; 
hence it used a default one with no arguments.


Cheers.
