Python Programming Playbook

Python is the language behind modern AI, Machine Learning and Data Science. It is also one of the easiest programming languages to start with. This playbook takes you from your first line of Python to writing small, complete programs you can run, change and show to others.

Instead of long theory, every chapter follows the same pattern. First you see why a concept matters. Then you get a plain-language explanation, a worked example with annotated code, and a short project where you put it to use. Each chapter ends with a checklist, and AI prompts you can use to practise further or get unstuck.

As you work through the playbook, you write a set of small programs, such as a command-line expense tracker, a quiz game, a file organiser and a weather app that calls a live API. Each one uses the skills from the chapters before it, so by the end you have a folder of working projects and the full source code for all of them.

You start with setting up Python and VS Code, then move through variables, data types, conditions, loops and functions. From there you work with lists, dictionaries and sets, read and write files, handle errors properly and organise code into modules. Later chapters introduce object-oriented programming with classes, working with JSON and CSV data, installing packages with pip, using virtual environments and calling REST APIs.

It is written for complete beginners, career changers and students who want a practical start in Python. It also suits developers from other languages who want a quick, project-based way to get comfortable with Python before moving into AI or Data Science.
