The Cursor object contains all the methods to execute quires and fetch data etc. In this tutorial, we’ll go through the sqlite3 module in Python 3. You can a connection object using the connect () function: import sqlite3 con nnect ('mydatabase. SQLite comes bundled with Python and can be used in any of your Python applications without having to install any additional software. To use SQLite3 in Python, first of all, you will have to import the sqlite3 module and then create a connection object which will connect us to the database and will let us execute the SQL statements. After creating a table, if you can verify the list of tables you can observe the newly created table in it as − Introduction SQLite is a self-contained, file-based SQL database. You can get the list of tables in a database in SQLite database using the. Let us create one more table OdiStats describing the One-day cricket statistics of each player in CRICKETERS table.
