Ordering in Descending Order by a Single Column

You can also use .order_by() to sort from highest to lowest by wrapping a column in the desc() function. Although you haven't seen this function in action, it generalizes what you have already learned.

All you have to just pass in desc() inside an .order_by() with the name of the column you want to sort by. For instance, stmt.order_by(desc(table.columns.column_name)) sorts column_name in descending order.

Import desc from the sqlalchemy module.
Select all records of the state column from the census table.
Append an .order_by() to sort the result output by the state column in descending order. Save the result as rev_stmt.
Execute rev_stmt using connection.execute() and fetch all the results with .fetchall(). Save them as rev_results.
Print the first 10 rows of rev_results.
