Python Level 2

Python Level 2 is the foundational course for Object-Oriented Programming (OOP), building upon the core concepts from Level 1. Students will learn to write structured, reusable code using classes and objects to create interactive simulations like Wandering Eyes, Bouncing Balls, and Rain. The course focuses on implementing motion, physics (gravity), data mapping, and managing multiple objects efficiently with lists, preparing students for advanced game and application logic in Python Level 3.

Why take this course?

In Python Level 1, students explored basic coding concepts and simple graphical projects. In this course, they will take their skills to the next level by learning how to organise and reuse code efficiently through Object-Oriented Programming (OOP).

Students will explore classes, objects, inheritance, and logic-based design while creating visual simulations like wandering eyes, bouncing balls, rain, and polka dots. By the end, students will understand how to structure code, animate objects, and build small-scale, interactive programs that mimic real-world physics and behaviour.

Prerequisites:

Students should have completed Python Level 1 or have prior experience with:
Writing and running Python code using conditionals, loops, and functions.
Working with coordinates or basic Processing sketches.
Understanding how variables control logic and behaviour in a program.
A typing speed of 35–40 WPM is recommended. Practice typing here:

Course Outline

4 Month Plan

1) Understanding Objects and Motion

a) Learning the Basics of Objects and Functions

Students will learn how to define setup() and draw() in Processing for animation and visual outputs.
They will create simple shapes with ellipse() and explore how to make elements respond using mouseX and mouseY.

b) Interactive Animation with Coordinates

Students will design animated eyes that follow the cursor, introducing how coordinates and object tracking work.
They will use the map() function to keep the pupils inside the eye boundaries, reinforcing geometry and logic in the Wandering Eyes project.

c) Introducing Classes and Object Properties

Students will understand how to define a class and create multiple objects with shared properties.
Students will see how attributes like size and colour can vary among instances, forming the base of OOP thinking.

d) Adding Interaction and Random Behaviour

Students will make the eyes behave independently using conditionals and randomisation for natural movement.
Students will explore how even simple code changes can create unique animations and reactions.

2) Motion and Gravity

a) Exploring Motion and Variables

Students will learn to use setup() and draw() for continuous animation and control object motion through variables.
Students will understand how to manipulate position (y) and velocity (vy) for realistic movement.

b) Dancing Balls Project

Students will simulate bouncing balls affected by gravity, using acceleration to change the object's speed over time.
Students will introduce lists and loops to manage multiple balls, each moving independently.

c) Simulating Real Physics

Students will use conditional statements to create collisions and simulate energy loss upon bouncing.
Students will observe how varying gravity or speed changes the animation outcome.

d) Experimenting and Debugging

Students will tweak variables and constants to explore how numeric values affect visual motion.
Students will practice debugging simple physics-based behaviours to achieve smooth, natural results.

3) Classes, Splash Effects, and Data Mapping

a) Structuring Complex Animations

Students will design the Rain Project, learning to manage multiple object types like Raindrop and Particle.
Students will use lists to store and update hundreds of objects efficiently in real time.

b) Creating Natural Effects with Classes

Students will code gravity and velocity into each raindrop and spawn splash particles on collision.
Students will understand how functions and helper methods like spawn_splash() support clean code organisation.

c) Introducing Mapping Concepts

Students will move into the Polka Dots Project, where the dots’ sizes change dynamically using the map() function.
Students will relate screen position (mouse movement) to data-driven visual control.

d) Managing Multiple Objects on Screen

Students will use lists to create and control many dots at once, each with unique speed, direction, and colour.
Students will implement edge detection logic so dots bounce off screen boundaries, introducing boundary conditions and event loops.

4) Real-World Programming and GUI Interaction

a) Connecting Logic with User Experience

Students will build simple login and signup forms with buttons, introducing GUI fundamentals.
Students will learn how text inputs, clicks, and events trigger program responses.

b) Working with File I/O

Students will read and write data (like usernames and passwords) using file handling in Python.
Students will validate and store user credentials, linking logic to persistent data storage.

c) Integrating OOP with Event-Driven Programming

Students will combine class-based design and GUI interaction in Replit’s Python environment.
Students will understand how mousePressed() and keyPressed() events drive program logic.

d) Extending Skills Toward Game Logic

As a preview of future challenges, students will see how classes, lists, and conditions form the basis for mini-games.
Students will explore how these same OOP concepts can evolve into logic-based games like Minesweeper in the next course level.

Learning Outcomes

Fluently apply Object-Oriented Programming (OOP) principles by defining classes, creating objects, and managing unique properties and behaviors for each instance.
Design and build complex, multi-object simulations that model realistic physics, including gravity, velocity, and collision detection, as demonstrated in the Bouncing Balls and Rain projects.
Effectively use lists and loops to manage and update hundreds of objects simultaneously, achieving efficient and scalable real-time animations.
Implement data mapping logic (like the map() function) to create dynamic and interactive visuals where object properties are directly controlled by user input or screen coordinates.
Build basic Graphical User Interfaces (GUIs) and integrate File I/O to create a functional login system, demonstrating the link between OOP, event-driven programming, and persistent data storage.
Be prepared for advanced game development and algorithmic challenges by mastering the core OOP, event, and animation concepts necessary for Python Level 3.

Learning to code helps build essential 21st-century skills such as critical thinking, problem-solving, and creativity. It fosters logical reasoning, boosts confidence in using technology, and prepares children for a future increasingly shaped by digital tools.

While we highly encourage punctuality and regular attendance, we understand that emergencies can happen. In such a case, parents must inform the instructor before the class and request a recording. In this way, the instructor can arrange a recording if informed in advance, as we do not usually record classes.
