A Pythonic Adventure: From Python basics to a working web app
Flask is a lightweight Python web application framework.
- How it is used
- Builds a first browser-accessible Python application, progressing from a local greeting to an interactive coffee-shop order form.
- How deep it goes
- Explains starter setup, routes, forms, requests, and templates through working examples, without descending into framework internals.
- Examples
- Uses a local greeting route and a coffee-shop menu that submits Coffee or Decaf and prints the selected drink.
- What you can do after
- Build it from scratch as a small Flask application that serves pages, accepts form input, and displays processed results.

The Well-Grounded Python Developer: How the pros use Python and Flask
Flask is a lightweight web application framework for Python that handles HTTP requests and connects URL resources to application code.
- How it is used
- Connects HTTP requests for URL resources to Python responses in a web-based blogging application.
- How deep it goes
- Works from a minimal route through dynamic templates, then shows sessions and error handlers without detailing a production server setup.
- Examples
- Uses a Hello World route, a current-time page, and a blogging application with session and error-page needs.
- What you can do after
- Build it from scratch as a small Flask server, then render a dynamic page and extend the application with sessions or error handlers.

Coding with AI
Flask is a lightweight Python web framework for building web applications and HTTP services.
- How it is used
- Supports Python web applications, HTTP services, database-backed pages, and REST APIs within small MVP-oriented projects.
- How deep it goes
- Explains initialization, routing, handlers, database retrieval, template rendering, and debug startup, without detailing advanced framework internals.
- Examples
- Uses TODO applications, a HAM radio practice test, SQLite questions, database models, and an index.html template.
- What you can do after
- Build a small Flask application that routes requests, reads database data, and renders an HTML page.
Machine Learning for Tabular Data: XGBoost, Deep Learning, and AI
Flask is a lightweight Python web framework for building web applications and HTTP request handlers.
- How it is used
- Deploys a trained machine-learning model locally as a small web application for demonstrations and beta-client testing.
- How deep it goes
- Explains routes, view functions, model loading, and request handling, while stopping short of comprehensive Flask coverage.
- Examples
- Uses a property-price prediction interface with home and results pages, model-loading code, routes, query strings, and tensor conversion.
- What you can do after
- Build a local Flask demonstration that accepts web inputs, invokes a saved Keras model, and renders its prediction.
