Create the table to the database
Having setup the engine and initialized the metadata, you will now define the census table object and then create it in the database using the metadata and engine from the previous exercise. To create it in the database, you will have to use the .create_all() method on the metadata with engine as the argument.
It may help to refer back to the Chapter 4 exercise in which you learned how to create a table.
