Use a class to model address data, advantage is that you can define
methods operating on address data, subclass address etc.

A dictionary gives you fast access to data by key. You could create
a dictionary of adresses that maps keys to addresses.

You can store such a dictionary with shelve module functions. Easy
to handle and sufficient if you don't need multi user access, an
SQL interface or have huge amount of data.
