The Quest Begins In the land of Codearia, where databases reign supreme, a brave adventurer named Pythonia embarked on a quest to master the ancient art of SQLite3. Her trusty steed, a Python interpreter, carried her through the realm of queries and data manipulation. The Journey Starts Pythonia began her journey by importing the sqlite3 module, a magical portal to the world of SQLite databases.
cursor.execute(''' CREATE TABLE IF NOT EXISTS inventory ( item TEXT, quantity INTEGER ) ''') sqlite3 tutorial query python fixed
# INSERT some data (optional) cursor.execute('INSERT INTO characters (name, health) VALUES ("Pythonia", 100)') cursor.execute('INSERT INTO inventory (item, quantity) VALUES ("sword", 1)')
# INSERT cursor.execute('INSERT INTO characters (name, health) VALUES ("Newbie", 50)') conn.commit() cursor
