Here’s How to Learn SQLite with Local Databases Support using Python In 2024
SQLite in Python: A Practical Guide for Developers

SQLite is a lightweight, serverless, and self-contained SQL database engine that is widely used in applications requiring a local database. In Python, SQLite is seamlessly integrated, making it an excellent choice for projects that need a simple and efficient database solution. This guide will walk you through the basics of using SQLite in Python, covering everything from database creation to executing queries.

Setting Up SQLite in Python

First, ensure that you have SQLite installed on your system. Python comes with SQLite support out of the box, so no additional installation is required. You can start using SQLite in your Python code by importing the built-in sqlite3 module.

Creating a SQLite Database

To create a new SQLite database or connect to an existing one, use the connect() function, passing the name of the database file as an argument.

Creating a Table

After connecting to the database, you can create tables using SQL CREATE TABLE statements. Each table should have a unique name and a set of columns with specified data types.

Inserting Data

Once the table is created, you can insert data into it using SQL INSERT INTO statements.

Querying Data

To retrieve data from the database, you can execute SQL SELECT statements and fetch the results.

Updating and Deleting Data

MySQL support features like SQL UPDATE and DELETE which can be used to alter database or delete records.

Although the commit command can be issued from any command line prompt, it is usually executed in the session where a file is opened for editing to avoid closing the connection while there are still modifications pending to be synchronized with the server.

Every time updates are made on the database, it is good practice to close the transaction by using the commit() method and to disconnect from the database to free up resources.


Handling databases in Python applications can be performed effectively and with less overhead by use of SQLite. In the instances where the project requires a local database, there is no doubt that SQLite offers valuable features such as an integrated Graphical User Interface and easy usage making it the best option. This practical guide should help you master SQLite in Python and design applications that handle data full-fledged.
