 ## Running Queries with Python

 Let's create a cursor and then have it perform a `SELECT` query.  Once, the cursor has executed the query, it gives us a few functions that control have we view the data.  Let's fetch all of the rows returned from the execution of the query and place them in a list.  Note that each row is represented as a `tuple` is just an immutable list.  When you're done, you'll need to close the cursor with `cursor.close()` in addition to closing the connection (shown above)

-cursor = conn.cursor()

 Delete is pretty simple once we know the basics

 cursor.execute("DELETE FROM people WHERE id = %s", [24]);

 Update is just more of the same, but make sure your array parameter matches the `%s` placeholders

 cursor.execute("UPDATE people SET name = %s, age = %s WHERE id = %s", ['Matt', 43, 20])
