cursor.execute('DELETE FROM characters WHERE name = "Rogue"') conn.commit() The rogue entity was vanquished, and the data was safely deleted from the characters table. As Pythonia concluded her quest, she closed the connection to the database, ensuring that her changes were saved.
cursor.execute('SELECT * FROM inventory WHERE quantity > 0') rows = cursor.fetchall() for row in rows: print(row) The wise old sage appeared once more, explaining that the WHERE clause was used to filter data based on conditions. In this case, Pythonia was retrieving only the rows where the quantity column was greater than 0. A fierce dragon, known as the UPDATE beast, guarded the treasure of modified data. Pythonia, armed with her trusty UPDATE statement, charged into battle.

conn.close() The people of Codearia celebrated Pythonia's mastery of SQLite3, and her legendary adventures were etched into the annals of database history. For those who wish to relive Pythonia's adventures, here is the complete code: cursor
cursor.execute(''' CREATE TABLE IF NOT EXISTS inventory ( item TEXT, quantity INTEGER ) ''')
# Close the connection conn.close()
# INSERT some data (optional) cursor.execute('INSERT INTO characters (name, health) VALUES ("Pythonia", 100)') cursor.execute('INSERT INTO inventory (item, quantity) VALUES ("sword", 1)')
