build Python web apps from the ground up
Flask is the Python web framework that teaches you how web development actually works. No magic, no hidden machinery. MyPyMentor's Web Development path takes you from your first route to a deployed, database-backed web app guided by Py, your AI tutor.
Every module ends with something real and working.
Write a Python function, add a decorator, and your browser loads a real web page. Flask makes the connection between Python and HTTP tangible from lesson one.
Create, read, update, and delete records in a SQLite database using SQLAlchemy — the same pattern used in production Flask applications.
Handle sign-up, hashed passwords, session management, and protected routes — the auth foundations every web app needs.
Return structured JSON from Flask endpoints so that a front-end, mobile app, or external service can consume your data programmatically.
Use Jinja2 to build dynamic HTML pages with shared layouts, loops, conditionals, and data passed from your Python views.
Push your app live so it runs on a server and anyone with the URL can reach it — not just on your laptop.
8 modules from first principles to a deployed, authenticated web application.
Flask does not hide the machinery. When you write a Flask app, you configure the routing, set up the database connection, decide how authentication works, and wire the pieces together yourself. That is more work than using Django — and it is precisely the point. You learn how each part of a web framework functions because you are the one building it.
Django does enormous amounts of work for you: an admin panel, a full ORM, built-in auth, automatic migrations. If you start with Django, you interact with all these abstractions before you understand what they abstract. When something breaks, you do not know where to look. When you start with Flask, nothing in Django feels mysterious — you recognise the pattern because you built it yourself first.
Flask is also the right tool for certain production systems independently of Django. REST APIs, ML model serving endpoints, and microservices frequently use Flask at scale precisely because of its minimal footprint. Learning Flask is not a step on the way to a real framework — it is learning a real framework that happens to teach web development from first principles.

“I had tried to learn web development twice before and always gave up at the database step. Flask on MyPyMentor was different — Py explained the ORM until it made sense, not just what to type.”

“I built my first real web app in 5 weeks. It has a login page, a database, and it is actually deployed live. I never thought I would get there this quickly.”

“The REST API module alone was worth it. I had a working API serving JSON in one session. Now our team consumes it from the React front-end. It felt like a superpower.”
