SQLite is an embedded SQL database that contains a C library. It is not a client-server database and instead embeds directly into the end program. SQLite follows PostgreSQL syntax. To connect with SQLite from Python, you import the sqlite3 module and use the connect() method to create a Connection object. From there you can create a Cursor object to execute SQL statements like CREATE TABLE, INSERT, SELECT, WHERE, ORDER BY, UPDATE, and DELETE.

- 5. Sqlite3 Establishing Connection Using Python You can communicate with SQLite2 database using the SQLite3 python module. To do so, first of all you need to establish a connection (create a connection object). To establish a connection with SQLite3 database using python you need to − Import the sqlite3 module using the import statement. The connect() method accepts the name of the database you need to connect with as a parameter and, returns a Connection object.
- 6. Sqlite3 Cursor The sqlite3.Cursor class is an instance using which you can invoke methods that execute SQLite statements, fetch data from the result sets of the queries. You can create Cursor object using the cursor() method of the Connection object/class.
- 7. Sqlite3 Python SQLite - Create Table Using the SQLite CREATE TABLE statement you can create a table in a database.
- 8. Sqlite3 Creating a Table Using Python The Cursor object contains all the methods to execute quires and fetch data etc. The cursor method of the connection class returns a cursor object. Therefore, to create a table in SQLite database using python − Establish connection with a database using the connect() method. Create a cursor object by invoking the cursor() method on the above created connection object. Now execute the CREATE TABLE statement using the execute() method of the Cursor class.
