Automatic joins with an established relationship

If you have two tables that already have an established relationship, you can automatically use that relationship by just adding the columns we want from each table to the select statement. Recall that Jason constructed the following query:

stmt = select([census.columns.pop2008, state_fact.columns.abbreviation])

in order to join the census and state_fact tables and select the pop2008 column from the first and the abbreviation column from the second. In this case, the census and state_fact tables had a pre-defined relationship: the state column of the former corresponded to the name column of the latter.

In this exercise, you'll use the same predefined relationship to select the pop2000 and abbreviation columns!

Build a statement to join the census and state_fact tables and select the pop2000 column from the first and the abbreviation column from the second.
Execute the statement to get the first result and save it as result.
Hit 'Submit Answer' to loop over the keys of the result object, and print the key and value for each!
