What Is a Function? 🧩🐍

Meet user-defined functions — named, reusable chunks of code. Learn to define functions with def, call them again and again, and discover why 'define before you call' matters.

Parameters: Passing Things In 📥🔧

Give your functions superpowers — pass information IN with parameters so one function can do its job on any name, number, or message you throw at it

Return Values: Getting Answers Back 📤✅

Learn the difference between print and return — how to hand a value back to your program, store it in a variable, and use it in maths, f-strings, and decisions

Scope & Function Design 🔍🏗️

Discover where variables live and die (local vs global), learn the golden rules of good function design, and refactor a messy program into tidy, well-named functions

Functions Working Together 🤝🔗

Make your functions a TEAM — functions that call other functions, default parameter values, and a menu that routes to a different function per choice (the exact skill behind next week's Text Adventure)

Designing Your Adventure 🗺️✍️

Plan and scaffold your own Text Adventure game. Learn the engine pattern — each scene is a function that returns the name of the next scene — story-map it on paper, and build a working 2-3 scene adventure you'll finish next week

Project: Text Adventure Engine 🗺️⚔️

Build a complete, polished multi-scene text adventure using the scene-function engine — with an inventory that unlocks choices, gated paths, and both winning and losing endings, all without a single crash

Adventure Showcase & Celebration! 🗺️🎭

Term 3 finale — polish and play-test your Text Adventure, give peer feedback, ace a fun functions quiz, and celebrate finishing the Functions term
