Filter data selected from a Table - Expressions

100xp

In addition to standard Python comparators, we can also use methods such as in_() to create more powerful where() clauses. You can see a full list of expressions in the SQLAlchemy Documentation.

We've already created a list of some of the most densely populated states.

Instructions

Select all records from the census table by passing it in as a list to select().
Append a where clause to return all the records with a state in the states list. Use in_(states) on census.columns.state to do this.
Loop over the ResultProxy connection.execute(stmt) and print the state and pop2000 columns from each record.
