How would one make Python objects persistent in a webapp

creating persistent python objects in a web application involves storing and retrieving data across multiple requests or sessions. there are several ways to achieve this, such as using databases, file storage, or caching mechanisms. in this tutorial, we'll focus on using a relational database, specifically sqlite, which is a lightweight and easy-to-use database that's often used for web applications during development.
we'll build a simple web application using the flask framework and sqlalchemy to demonstrate how to make python objects persistent. in this example, we'll create a web app for managing a list of tasks.
before you begin, ensure you have the following installed:
you can install flask and sqlalchemy using pip:
create a new directory for your project and create a python file (e.g., app.py) for your flask application:
in your project directory, create a folder called templates, and inside it, create an html file called index.html:
now that you've set up your flask application, you can run it using the following command:
visit http://localhost:5000 in your web browser, and you'll see a simple web app for managing tasks. you can add and delete tasks, and the data will be stored persistently in the sqlite database.
this tutorial demonstrates a basic example of how to make python objects persistent in a web app using flask and sqlalchemy. depending on your project's complexity and requirements, you might need to explore more advanced database options, such as postgresql or mysql, and implement user authentication and authorization for security.
