Programming Python: Web Development with Python. Building backend services and dynamic websites with a framework like Flask

Have you mastered Python syntax but still feel stuck writing scripts that only run on your own machine? Are you ready to take the next giant leap and build real-world applications that serve thousands of users?

Volume 3: Web Development with Python is your mission-critical guide to transforming your foundational Python knowledge into professional backend development skills. This hands-on, project-driven book demystifies the web, moving you from writing simple scripts to building robust, scalable, and secure web services from scratch.

Inside this guide, you'll learn how to:

Understand the Core of the Web: Master the client-server model and the HTTP protocol from the ground up.
Build with Flask: Use the elegant and powerful Flask micro-framework to create a complete backend API.
Manage Data Like a Pro: Connect your application to a persistent database using SQLAlchemy, the industry-standard Object-Relational Mapper (ORM).
Design RESTful APIs: Learn to build and consume modern APIs by returning structured JSON data and handling HTTP methods correctly.
Secure Your Application: Implement essential defenses against common web vulnerabilities like SQL Injection, XSS, and CSRF.
Handle User State: Master sessions, cookies, and token-based authentication to manage user logins and protect resources.
Prepare for Launch: Learn how to deploy your application for production using professional-grade tools like Gunicorn and Nginx.
This isn't just a reference manual; it's a guided expedition. Building on the skills from Volumes 1 and 2, this book is packed with clear diagrams, practical exercises, and detailed solutions designed not just to show you how, but to teach you why. You'll learn the architectural patterns—like Blueprints and Application Factories—that separate hobby projects from enterprise-grade systems.

Whether you want to build dynamic websites, powerful APIs for mobile apps, or the backend for AI services, this book provides the essential skills to make it happen.
