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.

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

SQLite supports features like SQL UPDATE and DELETE, which can be used to alter database records.
