SQLite

In web applications, you usually need a database, which is an organized collection of data. SQLite is a simple and fast open source SQL engine that can be used with Python to store and manipulate application data. SQLite works well with Python because the Python standard library provides the sqlite3 module, which you can use to interact with any SQLite database. In this tutorial, you’ll build a small web application that demonstrates how to use SQLite with Flask.

Learn how to use Flask-SQLAlchemy to manage databases in Flask. Create models, perform CRUD operations, and build scalable Python web apps.

Flask is a framework for building web applications using the Python language, and SQLite is a database engine that can be used with Python to store application data. In this tutorial, you will use Flask with SQLite to create a to-do application where users can create lists of to-do items. You will learn how to use SQLite with Flask and how one-to-many database relationships work.
