REST APIs with Flask and Python - Running the SQLite Database and Interacting with It from Python

This video tutorial provides an introduction to SQLite and demonstrates how to interact with a SQLite database using Python. It covers setting up the environment, connecting to a database, creating tables, inserting data, and retrieving data. The tutorial emphasizes the simplicity and lightweight nature of SQLite, while also highlighting its limitations compared to other SQL databases. By the end of the video, viewers will have a foundational understanding of how to use SQLite with Python for basic database operations.
