Summary

This CS50 lecture introduces Flask, a micro web framework for Python, as a tool to build web applications. The instructor begins by contrasting static web serving with dynamic server-side processing, explaining how URLs can map to functions rather than files. He demonstrates a minimal Flask app that returns ‘Hello, world’, then shows how to return HTML and use templates with Jinja. The lecture covers passing parameters via query strings, using the request object, and rendering templates with placeholders. It emphasizes the separation of logic (Python) and presentation (HTML templates). The instructor also discusses the importance of frameworks and libraries, and how Flask leverages Jinja for templating. The session is practical, with live coding examples in VS Code, and sets the foundation for more complex web applications in subsequent lessons.
