This module delves into the practical application of Python for web development through the exploration of Flask, a popular Python web framework. It starts by introducing Flask and Django, comparing their strengths and weaknesses to help learners understand their respective use cases. Learners then dive deep into Flask, starting with setting up their development environment and creating a basic Flask application. The module emphasizes core concepts such as routing and rendering, explaining how to handle different HTTP requests and dynamically generate web pages using templates. Through hands-on demos and activities, learners gain practical experience in building a simple web application using Flask, incorporating essential features like data handling, file management, and decorators. This module provides learners with a solid foundation in Flask, equipping them with the skills to develop dynamic and interactive web applications.

This module focuses on the crucial role of databases in web development and how to integrate them effectively with Python applications. Learners begin by exploring fundamental database concepts, including relational databases, SQL, and the importance of database schemas. They gain practical experience with SQL syntax through interactive exercises, focusing on essential commands for data manipulation. The module then introduces Object-Relational Mappers (ORMs) and their role in simplifying database interactions within Python. Learners delve into popular ORM libraries like Flask-SQLAlchemy, learning how to define models, establish relationships between tables, and perform CRUD operations. Through hands-on demos and projects, learners gain practical experience in setting up a database, designing schemas, and interacting with data using ORMs. This module bridges the gap between database theory and practical implementation, equipping learners with essential skills for building data-driven web applications.

This module introduces learners to the world of Application Programming Interfaces (APIs), focusing on the widely adopted RESTful architecture. It begins by explaining the core concepts of REST, including resources, endpoints, HTTP methods, and status codes. Learners explore how APIs facilitate communication between different software systems, enabling data exchange and integration. The module then explores the practical aspects of API development using Flask-RESTful, a Python framework for building RESTful APIs. Through live coding demonstrations and hands-on activities, learners gain experience in setting up API endpoints, handling requests and responses, and consuming external APIs. The module also covers security considerations, emphasizing the importance of authentication and authorization mechanisms to protect API access. By the end of this module, learners will have a solid understanding of RESTful APIs and the ability to create and integrate APIs into their web applications.

This module focuses on the crucial final steps of web development: deploying applications, implementing security measures, and understanding ongoing maintenance. Learners begin by exploring common web security threats and vulnerabilities, such as SQL injection and cross-site scripting (XSS), and learn how to mitigate these risks through secure coding practices. The module then delves into deployment strategies, comparing different cloud platforms like AWS and Heroku, and differentiating between PaaS and IaaS models. Learners gain practical experience by deploying a Flask application to a chosen platform, implementing basic security measures to protect their application from common attacks. This module provides learners with the essential skills and knowledge to launch secure and reliable web applications, ensuring their ongoing maintenance and protection.

This module emphasizes the critical role of testing in web development and introduces learners to essential testing techniques and tools. It begins by explaining the importance of testing in ensuring the quality, functionality, and user experience of web applications. Learners are then introduced to practical testing methods, including unit testing with Flask and automated testing with Selenium. Through demonstrations and hands-on activities, learners gain experience in writing and running tests, simulating user interactions, and identifying potential issues. The module also covers the ongoing maintenance and monitoring of web applications, highlighting the importance of keeping applications up-to-date, secure, and performing optimally. By the end of this module, learners will understand the value of testing throughout the development lifecycle and possess the skills to ensure their web applications are robust, reliable, and user-friendly.
