Using SQLite Database in Python Projects

Introduction

Databases play a crucial role in software development by enabling efficient storage, retrieval, and management of data. Python, a versatile and powerful programming language, offers various libraries to interact with different databases seamlessly. In this article, we will focus on SQLite, a lightweight, serverless, and self-contained database that is easy to set up and requires no external server. It comes built-in with Python, making it an excellent choice for beginners and small-scale projects.

To illustrate the relationship between SQLite and Python, we can follow this flow of interactions:

1. Python: The programming language used to interact with SQLite.
2. sqlite3: The built-in Python library used to interact with SQLite databases.
3. Connection: The object that represents the connection between Python and the SQLite database.
4. Cursor: The object used to interact with the database, execute SQL queries, and fetch results.
5. SQL Commands: The SQL statements used to create, read, update, and delete data in the SQLite database.
6. Database File: The SQLite database file (.db) that stores the data.
