I am writing a class to provide a db backed configuration for an 
application.
In my programs code, I import the class and pass the ODBC params to the
class for its __init__ to instantiate a connection.
I would like to create a function to generically access a table and provide 
an
iterator. How does one create a function in a class that takes an argument 
and
returns an iterator? I saw some examples where the class gets instantiated
with the table defined but I was hoping not to do this so I could continue 
to
access various tables through one connection/cursor.
Thanks!

Python makes it easy. Read up on "Generators", and the "yield" statement. 
Works very elegantly with a "for ... in" loop.
